+Description
+
+  DRBD is a shared-nothing, synchronously replicated block device. It
+  is designed to serve as a building block for high availability
+  clusters and in this context, is a "drop-in" replacement for shared
+  storage. Simplistically, you could see it as a network RAID 1.
+
+  Please visit http://www.drbd.org to find out more.
+
+The here included files are intended to help understand the implementation
+
+DRBD-8.3-data-packets.svg, DRBD-data-packets.svg  
+  relates some functions, and write packets.

+Description
+-----------
+
+The Freescale MC13783 is a Power Management and Audio Circuit. Among
+other things it contains a 10-bit A/D converter. The converter has 16
+channels which can be used in different modes.
+The A/D converter has a resolution of 2.25mV. Channels 0-4 have
+a dedicated meaning with chip internal scaling applied. Channels 5-7
+can be used as general purpose inputs or alternatively in a dedicated
+mode. Channels 12-15 are occupied by the touchscreen if it's active.
+
+Currently the driver only supports channels 2 and 5-15 with no alternative
+modes for channels 5-7.
+
+See this table for the meaning of the different channels and their chip
+internal scaling:

+This was meant as a workaround for mainboards with a broken BIOS. This
+module parameter is gone for technical reasons. If you need this feature,
+you can obtain the same result by using the isaset tool (part of
+lm-sensors) before loading the driver:
+
+# Enter the Super I/O config space
+isaset -y -f 0x2e 0x87
+isaset -y -f 0x2e 0x87
+
+# Select the hwmon logical device
+isaset -y 0x2e 0x2f 0x07 0x0b
+
+# Set the base I/O address (to 0x290 in this example)
+isaset -y 0x2e 0x2f 0x60 0x02
+isaset -y 0x2e 0x2f 0x61 0x90
+
+# Exit the Super-I/O config space
+isaset -y -f 0x2e 0xaa
+
+The above sequence assumes a Super-I/O config space at 0x2e/0x2f, but
+0x4e/0x4f is also possible.

-
-Main contact: Philip Edelbrock <phil@netroedge.com>
-	
-The code is based upon Ralph's test code (he did the hard stuff ;')
-
-Description
------------
-
-The 3dfx Voodoo3 chip contains two I2C interfaces (aka a I2C 'master' or
-'host'). 
-
-The first interface is used for DDC (Data Display Channel) which is a
-serial channel through the VGA monitor connector to a DDC-compliant
-monitor. This interface is defined by the Video Electronics Standards
-Association (VESA). The standards are available for purchase at
-http://www.vesa.org .
-
-The second interface is a general-purpose I2C bus. The intent by 3dfx was
-to allow manufacturers to add extra chips to the video card such as a
-TV-out chip such as the BT869 or possibly even I2C based temperature
-sensors like the ADM1021 or LM75.
-
-Stability
----------
-
-Seems to be stable on the test machine, but needs more testing on other
-machines. Simultaneous accesses of the DDC and I2C busses may cause errors.
-
-Supported Devices
------------------
-
-Specifically, this driver was written and tested on the '3dfx Voodoo3 AGP
-3000' which has a tv-out feature (s-video or composite).  According to the
-docs and discussions, this code should work for any Voodoo3 based cards as
-well as Voodoo Banshee based cards.  The DDC interface has been tested on a
-Voodoo Banshee card.
-	
-Issues
-------
-
-Probably many, but it seems to work OK on my system. :')
-
-
-External Device Connection
---------------------------
-
-The digital video input jumpers give availability to the I2C bus. 
-Specifically, pins 13 and 25 (bottom row middle, and bottom right-end) are     
-the I2C clock and I2C data lines, respectively. +5V and GND are probably
-also easily available making the addition of extra I2C/SMBus devices easy
-to implement.

+I2C device driver binding control from user-space
+=================================================
+
+Up to kernel 2.6.32, many i2c drivers used helper macros provided by
+<linux/i2c.h> which created standard module parameters to let the user
+control how the driver would probe i2c buses and attach to devices. These
+parameters were known as "probe" (to let the driver probe for an extra
+address), "force" (to forcibly attach the driver to a given device) and
+"ignore" (to prevent a driver from probing a given address).
+
+With the conversion of the i2c subsystem to the standard device driver
+binding model, it became clear that these per-module parameters were no
+longer needed, and that a centralized implementation was possible. The new,
+sysfs-based interface is described in the documentation file
+"instantiating-devices", section "Method 4: Instantiate from user-space".
+
+Below is a mapping from the old module parameters to the new interface.
+
+Attaching a driver to an I2C device
+-----------------------------------
+
+Old method (module parameters):
+# modprobe <driver> probe=1,0x2d
+# modprobe <driver> force=1,0x2d
+# modprobe <driver> force_<device>=1,0x2d
+
+New method (sysfs interface):
+# echo <device> 0x2d > /sys/bus/i2c/devices/i2c-1/new_device
+
+Preventing a driver from attaching to an I2C device
+---------------------------------------------------
+
+Old method (module parameters):
+# modprobe <driver> ignore=1,0x2f
+
+New method (sysfs interface):
+# echo dummy 0x2f > /sys/bus/i2c/devices/i2c-1/new_device
+# modprobe <driver>
+
+Of course, it is important to instantiate the "dummy" device before loading
+the driver. The dummy device will be handled by i2c-core itself, preventing
+other drivers from binding to it later on. If there is a real device at the
+problematic address, and you want another driver to bind to it, then simply
+pass the name of the device in question instead of "dummy".

- * The locking is really quite interesting.  There's a cpu-local
- * count of how many interrupts are being handled, and a global
- * lock.  An interrupt can only be serviced if the global lock
- * is free.  You can't be sure no more interrupts are being
- * serviced until you've acquired the lock and then checked
- * all the per-cpu interrupt counts are all zero.  It's a specialised
- * br_lock, and that's exactly how Sparc does it.  We don't because
- * it's more locking for us.  This way is lock-free in the interrupt path.

+
+	  NOTE: In order to authenticate connections you have to select
+	  CRYPTO_HMAC and a hash function as well.
+
+	  DRBD is a shared-nothing, synchronously replicated block device. It
+	  is designed to serve as a building block for high availability
+	  clusters and in this context, is a "drop-in" replacement for shared
+	  storage. Simplistically, you could see it as a network RAID 1.
+
+	  Each minor device has a role, which can be 'primary' or 'secondary'.
+	  On the node with the primary device the application is supposed to
+	  run and to access the device (/dev/drbdX). Every write is sent to
+	  the local 'lower level block device' and, across the network, to the
+	  node with the device in 'secondary' state.  The secondary device
+	  simply writes the data to its lower level block device.
+
+	  DRBD can also be used in dual-Primary mode (device writable on both
+	  nodes), which means it can exhibit shared disk semantics in a
+	  shared-nothing cluster.  Needless to say, on top of dual-Primary
+	  DRBD utilizing a cluster file system is necessary to maintain for
+	  cache coherency.
+
+	  For automatic failover you need a cluster manager (e.g. heartbeat).
+	  See also: http://www.drbd.org/, http://www.linux-ha.org
+
+	  If unsure, say N.
+

+
+	  Say Y here if you want to simulate IO errors, in order to test DRBD's
+	  behavior.
+
+	  The actual simulation of IO errors is done by writing 3 values to
+	  /sys/module/drbd/parameters/
+
+	  enable_faults: bitmask of...
+	  1	meta data write
+	  2               read

+	  128	kmalloc of bitmap
+	  256	allocation of EE (epoch_entries)
+
+	  fault_devs: bitmask of minor numbers
+	  fault_rate: frequency in percent

+ * At a granularity of 4KiB storage represented per bit,
+ * and stroage sizes of several TiB,
+ * and possibly small-bandwidth replication,
+ * the bitmap transfer time can take much too long,
+ * if transmitted in plain text.
+ *
+ * We try to reduce the transfered bitmap information
+ * by encoding runlengths of bit polarity.
+ *
+ * We never actually need to encode a "zero" (runlengths are positive).
+ * But then we have to store the value of the first bit.
+ * The first bit of information thus shall encode if the first runlength
+ * gives the number of set or unset bits.
+ *
+ * We assume that large areas are either completely set or unset,
+ * which gives good compression with any runlength method,
+ * even when encoding the runlength as fixed size 32bit/64bit integers.
+ *
+ * Still, there may be areas where the polarity flips every few bits,
+ * and encoding the runlength sequence of those areas with fix size
+ * integers would be much worse than plaintext.
+ *
+ * We want to encode small runlength values with minimum code length,
+ * while still being able to encode a Huge run of all zeros.
+ *
+ * Thus we need a Variable Length Integer encoding, VLI.
+ *
+ * For some cases, we produce more code bits than plaintext input.
+ * We need to send incompressible chunks as plaintext, skip over them
+ * and then see if the next chunk compresses better.
+ *
+ * We don't care too much about "excellent" compression ratio for large
+ * runlengths (all set/all clear): whether we achieve a factor of 100
+ * or 1000 is not that much of an issue.
+ * We do not want to waste too much on short runlengths in the "noisy"
+ * parts of the bitmap, though.
+ *
+ * There are endless variants of VLI, we experimented with:
+ *  * simple byte-based
+ *  * various bit based with different code word length.
+ *
+ * To avoid yet an other configuration parameter (choice of bitmap compression
+ * algorithm) which was difficult to explain and tune, we just chose the one
+ * variant that turned out best in all test cases.
+ * Based on real world usage patterns, with device sizes ranging from a few GiB
+ * to several TiB, file server/mailserver/webserver/mysql/postgress,
+ * mostly idle to really busy, the all time winner (though sometimes only
+ * marginally better) is:

+
+/*
+ * encoding is "visualised" as
+ * __little endian__ bitstream, least significant bit first (left most)
+ *
+ * this particular encoding is chosen so that the prefix code
+ * starts as unary encoding the level, then modified so that
+ * 10 levels can be described in 8bit, with minimal overhead
+ * for the smaller levels.
+ *
+ * Number of data bits follow fibonacci sequence, with the exception of the
+ * last level (+1 data bit, so it makes 64bit total).  The only worse code when
+ * encoding bit polarity runlength is 1 plain bits => 2 code bits.

-/**
- * ath5k_hw_set_bssid_mask - filter out bssids we listen
- *
- * @ah: the &struct ath5k_hw
- * @mask: the bssid_mask, a u8 array of size ETH_ALEN
- *
- * BSSID masking is a method used by AR5212 and newer hardware to inform PCU
- * which bits of the interface's MAC address should be looked at when trying
- * to decide which packets to ACK. In station mode and AP mode with a single
- * BSS every bit matters since we lock to only one BSS. In AP mode with
- * multiple BSSes (virtual interfaces) not every bit matters because hw must
- * accept frames for all BSSes and so we tweak some bits of our mac address
- * in order to have multiple BSSes.
- *
- * NOTE: This is a simple filter and does *not* filter out all
- * relevant frames. Some frames that are not for us might get ACKed from us
- * by PCU because they just match the mask.
- *
- * When handling multiple BSSes you can get the BSSID mask by computing the
- * set of  ~ ( MAC XOR BSSID ) for all bssids we handle.
- *
- * When you do this you are essentially computing the common bits of all your
- * BSSes. Later it is assumed the harware will "and" (&) the BSSID mask with
- * the MAC address to obtain the relevant bits and compare the result with
- * (frame's BSSID & mask) to see if they match.
- */
-/*
- * Simple example: on your card you have have two BSSes you have created with
- * BSSID-01 and BSSID-02. Lets assume BSSID-01 will not use the MAC address.
- * There is another BSSID-03 but you are not part of it. For simplicity's sake,
- * assuming only 4 bits for a mac address and for BSSIDs you can then have:
- *
- *                  \
- * MAC:                0001 |
- * BSSID-01:   0100 | --> Belongs to us
- * BSSID-02:   1001 |
- *                  /
- * -------------------
- * BSSID-03:   0110  | --> External
- * -------------------
- *
- * Our bssid_mask would then be:
- *
- *             On loop iteration for BSSID-01:
- *             ~(0001 ^ 0100)  -> ~(0101)
- *                             ->   1010
- *             bssid_mask      =    1010
- *
- *             On loop iteration for BSSID-02:
- *             bssid_mask &= ~(0001   ^   1001)
- *             bssid_mask =   (1010)  & ~(0001 ^ 1001)
- *             bssid_mask =   (1010)  & ~(1001)
- *             bssid_mask =   (1010)  &  (0110)
- *             bssid_mask =   0010
- *
- * A bssid_mask of 0010 means "only pay attention to the second least
- * significant bit". This is because its the only bit common
- * amongst the MAC and all BSSIDs we support. To findout what the real
- * common bit is we can simply "&" the bssid_mask now with any BSSID we have
- * or our MAC address (we assume the hardware uses the MAC address).
- *
- * Now, suppose there's an incoming frame for BSSID-03:
- *
- * IFRAME-01:  0110
- *
- * An easy eye-inspeciton of this already should tell you that this frame
- * will not pass our check. This is beacuse the bssid_mask tells the
- * hardware to only look at the second least significant bit and the
- * common bit amongst the MAC and BSSIDs is 0, this frame has the 2nd LSB
- * as 1, which does not match 0.
- *
- * So with IFRAME-01 we *assume* the hardware will do:
- *
- *     allow = (IFRAME-01 & bssid_mask) == (bssid_mask & MAC) ? 1 : 0;
- *  --> allow = (0110 & 0010) == (0010 & 0001) ? 1 : 0;
- *  --> allow = (0010) == 0000 ? 1 : 0;
- *  --> allow = 0
- *
- *  Lets now test a frame that should work:
- *
- * IFRAME-02:  0001 (we should allow)
- *
- *     allow = (0001 & 1010) == 1010
- *
- *     allow = (IFRAME-02 & bssid_mask) == (bssid_mask & MAC) ? 1 : 0;
- *  --> allow = (0001 & 0010) ==  (0010 & 0001) ? 1 :0;
- *  --> allow = (0010) == (0010)
- *  --> allow = 1
- *
- * Other examples:
- *
- * IFRAME-03:  0100 --> allowed
- * IFRAME-04:  1001 --> allowed
- * IFRAME-05:  1101 --> allowed but its not for us!!!

- * ath5k_hw_noise_floor_calibration - perform PHY noise floor calibration
- *
- * @ah: struct ath5k_hw pointer we are operating on
- * @freq: the channel frequency, just used for error logging
- *
- * This function performs a noise floor calibration of the PHY and waits for
- * it to complete. Then the noise floor value is compared to some maximum
- * noise floor we consider valid.
- *
- * Note that this is different from what the madwifi HAL does: it reads the
- * noise floor and afterwards initiates the calibration. Since the noise floor
- * calibration can take some time to finish, depending on the current channel
- * use, that avoids the occasional timeout warnings we are seeing now.
- *
- * See the following link for an Atheros patent on noise floor calibration:
- * http://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO1&Sect2=HITOFF&d=PALL \

+/**
+ * ath_hw_set_bssid_mask - filter out bssids we listen
+ *
+ * @common: the ath_common struct for the device.
+ *
+ * BSSID masking is a method used by AR5212 and newer hardware to inform PCU
+ * which bits of the interface's MAC address should be looked at when trying
+ * to decide which packets to ACK. In station mode and AP mode with a single
+ * BSS every bit matters since we lock to only one BSS. In AP mode with
+ * multiple BSSes (virtual interfaces) not every bit matters because hw must
+ * accept frames for all BSSes and so we tweak some bits of our mac address
+ * in order to have multiple BSSes.
+ *
+ * NOTE: This is a simple filter and does *not* filter out all
+ * relevant frames. Some frames that are not for us might get ACKed from us
+ * by PCU because they just match the mask.
+ *
+ * When handling multiple BSSes you can get the BSSID mask by computing the
+ * set of  ~ ( MAC XOR BSSID ) for all bssids we handle.
+ *
+ * When you do this you are essentially computing the common bits of all your
+ * BSSes. Later it is assumed the harware will "and" (&) the BSSID mask with
+ * the MAC address to obtain the relevant bits and compare the result with
+ * (frame's BSSID & mask) to see if they match.
+ *
+ * Simple example: on your card you have have two BSSes you have created with
+ * BSSID-01 and BSSID-02. Lets assume BSSID-01 will not use the MAC address.
+ * There is another BSSID-03 but you are not part of it. For simplicity's sake,
+ * assuming only 4 bits for a mac address and for BSSIDs you can then have:
+ *
+ *                  \
+ * MAC:        0001 |
+ * BSSID-01:   0100 | --> Belongs to us
+ * BSSID-02:   1001 |
+ *                  /
+ * -------------------
+ * BSSID-03:   0110  | --> External
+ * -------------------
+ *
+ * Our bssid_mask would then be:
+ *
+ *             On loop iteration for BSSID-01:
+ *             ~(0001 ^ 0100)  -> ~(0101)
+ *                             ->   1010
+ *             bssid_mask      =    1010
+ *
+ *             On loop iteration for BSSID-02:
+ *             bssid_mask &= ~(0001   ^   1001)
+ *             bssid_mask =   (1010)  & ~(0001 ^ 1001)
+ *             bssid_mask =   (1010)  & ~(1001)
+ *             bssid_mask =   (1010)  &  (0110)
+ *             bssid_mask =   0010
+ *
+ * A bssid_mask of 0010 means "only pay attention to the second least
+ * significant bit". This is because its the only bit common
+ * amongst the MAC and all BSSIDs we support. To findout what the real
+ * common bit is we can simply "&" the bssid_mask now with any BSSID we have
+ * or our MAC address (we assume the hardware uses the MAC address).
+ *
+ * Now, suppose there's an incoming frame for BSSID-03:
+ *
+ * IFRAME-01:  0110
+ *
+ * An easy eye-inspeciton of this already should tell you that this frame
+ * will not pass our check. This is beacuse the bssid_mask tells the
+ * hardware to only look at the second least significant bit and the
+ * common bit amongst the MAC and BSSIDs is 0, this frame has the 2nd LSB
+ * as 1, which does not match 0.
+ *
+ * So with IFRAME-01 we *assume* the hardware will do:
+ *
+ *     allow = (IFRAME-01 & bssid_mask) == (bssid_mask & MAC) ? 1 : 0;
+ *  --> allow = (0110 & 0010) == (0010 & 0001) ? 1 : 0;
+ *  --> allow = (0010) == 0000 ? 1 : 0;
+ *  --> allow = 0
+ *
+ *  Lets now test a frame that should work:
+ *
+ * IFRAME-02:  0001 (we should allow)
+ *
+ *     allow = (0001 & 1010) == 1010
+ *
+ *     allow = (IFRAME-02 & bssid_mask) == (bssid_mask & MAC) ? 1 : 0;
+ *  --> allow = (0001 & 0010) ==  (0010 & 0001) ? 1 :0;
+ *  --> allow = (0010) == (0010)
+ *  --> allow = 1
+ *
+ * Other examples:
+ *
+ * IFRAME-03:  0100 --> allowed
+ * IFRAME-04:  1001 --> allowed
+ * IFRAME-05:  1101 --> allowed but its not for us!!!

+========================
+power period
+
+	This command is used to configure the station in deep sleep mode /
+	auto deep sleep mode.
+
+	The timer is implemented to monitor the activities (command, event,
+	etc.). When an activity is detected station will exit from deep
+	sleep mode automatically and restart the timer. At timer expiry
+	(no activity for defined time period) the deep sleep mode is entered
+	automatically.
+
+	Note: this command is for SDIO interface only.
+
+	Usage:
+	To enable deep sleep mode do:
+		iwconfig wlan0 power period 0
+	To enable auto deep sleep mode with idle time period 5 seconds do:
+		iwconfig wlan0 power period 5
+	To disable deep sleep/auto deep sleep mode do:
+		iwconfig wlan0 power period -1

-	  Cowloop is a "copy-on-write" pseudo block driver. It can be
-	  stacked on top of a "real" block driver, and catches all write
-	  operations on their way from the file systems layer above to
-	  the real driver below, effectively shielding the lower driver
-	  from those write accesses. The requests are then diverted to
-	  an ordinary file, located somewhere else (configurable). Later
-	  read requests are checked to see whether they can be serviced
-	  by the "real" block driver below, or must be pulled in from
-	  the diverted location. More information and userspace tools to
-	  use the driver are on the project's website

-**       COWLOOP block device driver (2.6 kernel compliant)
-** =======================================================================
-** Read-write loop-driver with copy-on-write functionality.
-**
-** Synopsis:
-**
-**     modprobe cowloop [maxcows=..] [rdofile=..... cowfile=.... [option=r]]
-**
-** Definition of number of configured cowdevices:
-**   maxcows=	number of configured cowdevices (default: 16)
-** (do not confuse this with MAXCOWS: absolute maximum as compiled)
-**
-** One pair of filenames can be supplied during insmod/modprobe to open
-** the first cowdevice:
-**   rdofile=	read-only file (or filesystem)
-**   cowfile=	storage-space for modified blocks of read-only file(system)
-**   option=r	repair cowfile automatically if it appears to be dirty
-**
-** Other cowdevices can be activated via the command "cowdev"
-** whenever the cowloop-driver is loaded.
-**
-** The read-only file may be of type 'regular' or 'block-device'.
-**
-** The cowfile must be of type 'regular'.
-** If an existing regular file is used as cowfile, its contents will be
-** used again for the current read-only file. When the cowfile has not been
-** closed properly during a previous session (i.e. rmmod cowloop), the
-** cowloop-driver refuses to open it unless the parameter "option=r" is
-** specified.
-**
-** Layout of cowfile:
-**
-** 	+-----------------------------+
-**	|       cow head block        |   MAPUNIT bytes
-**	|-----------------------------|
-**	|                             |   MAPUNIT bytes
-**	|---                       ---|
-**	|                             |   MAPUNIT bytes
-**	|---                       ---|
-**	|      used-block bitmap      |   MAPUNIT bytes
-**	|-----------------------------|
-**	|  gap to align start-offset  |
-**	|        to 4K multiple       |
-**	|-----------------------------|  <---- start-offset cow blocks
-**	|                             |
-**      |    written cow blocks       |   MAPUNIT bytes
-**      |          .....              |
-**
-** 	cowhead block:
-**   	  - contains general info about the rdofile which is related
-** 	    to this cowfile
-**
-** 	used-block bitmap:
-** 	  - contains one bit per block with a size of MAPUNIT bytes
-** 	  - bit-value '1' = block has been written on cow
-** 	              '0' = block unused on cow
-** 	  - total bitmap rounded to multiples of MAPUNIT

-**	200507	Check for free space to expand cowfile.	Gerlof Langeveld
-**	200902  Upgrade for kernel 2.6.28               Hendrik-Jan Thomassen
-**
-** Inspired by
-**    loop.c  by Theodore Ts'o and
-**    cloop.c by Paul `Rusty' Russell & Klaus Knopper.
-**
-** Design-considerations:
-**
-**   For the first experiments with the cowloop-driver, the request-queue
-**   made use of the do_generic_file_read() which worked fine except
-**   in combination with the cloop-driver; that combination
-**   resulted in a non-interruptible hangup of the system during
-**   heavy load. Other experiments using the `make_request' interface also
-**   resulted in unpredictable system hangups (with proper use of spinlocks).
-**
-**   To overcome these problems, the cowloop-driver starts a kernel-thread
-**   for every active cowdevice.
-**   All read- and write-request on the read-only file and copy-on-write file
-**   are handled in the context of that thread.
-**   A scheme has been designed to wakeup the kernel-thread as
-**   soon as I/O-requests are available in the request-queue; this thread
-**   handles the requests one-by-one by calling the proper read- or
-**   write-function related to the open read-only file or copy-on-write file.
-**   When all pending requests have been handled, the kernel-thread goes
-**   back to sleep-state.
-**   This approach requires some additional context-switches; however the
-**   performance loss during heavy I/O is less than 3%.
-**

+This header file (and its .c file; kernel-doc of functions see there)
+  define a helper framework to easily keep track of index:label associations,
+  and changes to an "active set" of objects, as well as pending transactions,
+  to persistently record those changes.
+
+  We use an LRU policy if it is necessary to "cool down" a region currently in
+  the active set before we can "heat" a previously unused region.
+
+  Because of this later property, it is called "lru_cache".
+  As it actually Tracks Objects in an Active SeT, we could also call it
+  toast (incidentally that is what may happen to the data on the
+  backend storage uppon next resync, if we don't get it right).
+
+What for?
+
+We replicate IO (more or less synchronously) to local and remote disk.
+
+For crash recovery after replication node failure,
+  we need to resync all regions that have been target of in-flight WRITE IO
+  (in use, or "hot", regions), as we don't know wether or not those WRITEs have
+  made it to stable storage.
+
+  To avoid a "full resync", we need to persistently track these regions.
+
+  This is known as "write intent log", and can be implemented as on-disk
+  (coarse or fine grained) bitmap, or other meta data.
+
+  To avoid the overhead of frequent extra writes to this meta data area,
+  usually the condition is softened to regions that _may_ have been target of
+  in-flight WRITE IO, e.g. by only lazily clearing the on-disk write-intent
+  bitmap, trading frequency of meta data transactions against amount of
+  (possibly unneccessary) resync traffic.
+
+  If we set a hard limit on the area that may be "hot" at any given time, we
+  limit the amount of resync traffic needed for crash recovery.
+
+For recovery after replication link failure,
+  we need to resync all blocks that have been changed on the other replica
+  in the mean time, or, if both replica have been changed independently [*],
+  all blocks that have been changed on either replica in the mean time.
+  [*] usually as a result of a cluster split-brain and insufficient protection.
+      but there are valid use cases to do this on purpose.
+
+  Tracking those blocks can be implemented as "dirty bitmap".
+  Having it fine-grained reduces the amount of resync traffic.
+  It should also be persistent, to allow for reboots (or crashes)
+  while the replication link is down.
+
+There are various possible implementations for persistently storing
+write intent log information, three of which are mentioned here.
+
+"Chunk dirtying"
+  The on-disk "dirty bitmap" may be re-used as "write-intent" bitmap as well.
+  To reduce the frequency of bitmap updates for write-intent log purposes,
+  one could dirty "chunks" (of some size) at a time of the (fine grained)
+  on-disk bitmap, while keeping the in-memory "dirty" bitmap as clean as
+  possible, flushing it to disk again when a previously "hot" (and on-disk
+  dirtied as full chunk) area "cools down" again (no IO in flight anymore,
+  and none expected in the near future either).
+
+"Explicit (coarse) write intent bitmap"
+  An other implementation could chose a (probably coarse) explicit bitmap,
+  for write-intent log purposes, additionally to the fine grained dirty bitmap.
+
+"Activity log"
+  Yet an other implementation may keep track of the hot regions, by starting
+  with an empty set, and writing down a journal of region numbers that have
+  become "hot", or have "cooled down" again.
+
+  To be able to use a ring buffer for this journal of changes to the active
+  set, we not only record the actual changes to that set, but also record the
+  not changing members of the set in a round robin fashion. To do so, we use a
+  fixed (but configurable) number of slots which we can identify by index, and
+  associate region numbers (labels) with these indices.
+  For each transaction recording a change to the active set, we record the
+  change itself (index: -old_label, +new_label), and which index is associated
+  with which label (index: current_label) within a certain sliding window that
+  is moved further over the available indices with each such transaction.
+
+  Thus, for crash recovery, if the ringbuffer is sufficiently large, we can
+  accurately reconstruct the active set.
+
+  Sufficiently large depends only on maximum number of active objects, and the
+  size of the sliding window recording "index: current_label" associations within
+  each transaction.
+
+  This is what we call the "activity log".
+
+  Currently we need one activity log transaction per single label change, which
+  does not give much benefit over the "dirty chunks of bitmap" approach, other
+  than potentially less seeks.
+
+  We plan to change the transaction format to support multiple changes per
+  transaction, which then would reduce several (disjoint, "random") updates to
+  the bitmap into one transaction to the activity log ring buffer.
+*/
+
+/* this defines an element in a tracked set
+ * .colision is for hash table lookup.
+ * When we process a new IO request, we know its sector, thus can deduce the
+ * region number (label) easily.  To do the label -> object lookup without a
+ * full list walk, we use a simple hash table.
+ *
+ * .list is on one of three lists:
+ *  in_use: currently in use (refcnt > 0, lc_number != LC_FREE)
+ *     lru: unused but ready to be reused or recycled
+ *          (ts_refcnt == 0, lc_number != LC_FREE),
+ *    free: unused but ready to be recycled
+ *          (ts_refcnt == 0, lc_number == LC_FREE),
+ *
+ * an element is said to be "in the active set",
+ * if either on "in_use" or "lru", i.e. lc_number != LC_FREE.
+ *
+ * DRBD currently (May 2009) only uses 61 elements on the resync lru_cache
+ * (total memory usage 2 pages), and up to 3833 elements on the act_log
+ * lru_cache, totalling ~215 kB for 64bit architechture, ~53 pages.
+ *
+ * We usually do not actually free these objects again, but only "recycle"
+ * them, as the change "index: -old_label, +LC_FREE" would need a transaction
+ * as well.  Which also means that using a kmem_cache to allocate the objects
+ * from wastes some resources.
+ * But it avoids high order page allocations in kmalloc.

+ *
+ * - A LIFO list of node-local objects. Allocation and freeing of node local
+ *   objects goes first to this list.
+ *
+ * - 2 Lists of slab pages, free and partial pages. If an allocation misses
+ *   the object list, it tries from the partial list, then the free list.
+ *   After freeing an object to the object list, if it is over a watermark,
+ *   some objects are freed back to pages. If an allocation misses these lists,
+ *   a new slab page is allocated from the page allocator. If the free list
+ *   reaches a watermark, some of its pages are returned to the page allocator.
+ *
+ * - A remote free queue, where objects freed that did not come from the local
+ *   node are queued to. When this reaches a watermark, the objects are
+ *   flushed.
+ *
+ * - A remotely freed queue, where objects allocated from this CPU are flushed
+ *   to from other CPUs' remote free queues. kmem_cache_remote_free->lock is
+ *   used to protect access to this queue.
+ *
+ *   When the remotely freed queue reaches a watermark, a flag is set to tell
+ *   the owner CPU to check it. The owner CPU will then check the queue on the
+ *   next allocation that misses the object list. It will move all objects from
+ *   this list onto the object list and then allocate one.
+ *
+ *   This system of remote queueing is intended to reduce lock and remote
+ *   cacheline acquisitions, and give a cooling off period for remotely freed
+ *   objects before they are re-allocated.
+ *
+ * node specific allocations from somewhere other than the local node are
+ * handled by a per-node list which is the same as the above per-CPU data
+ * structures except for the following differences:
+ *
+ * - kmem_cache_node->list_lock is used to protect access for multiple CPUs to
+ *   allocate from a given node.
+ *

+	  IPv4 encapsulation in order to transit IPv4-only network
+	  infrastructure.  Unlike 6to4, a 6rd service provider uses an IPv6
+	  prefix of its own in place of the fixed 6to4 prefix.
+
+	  With this option enabled, the SIT driver offers 6rd functionality by
+	  providing additional ioctl API to configure the IPv6 Prefix for in

-/*
- * API definition :
- * --------------
- * See <linux/wireless.h> for details of the APIs and the rest.
- *
- * History :
- * -------
- *
- * v1 - 5.12.01 - Jean II
- *	o Created this file.
- *
- * v2 - 13.12.01 - Jean II
- *	o Move /proc/net/wireless stuff from net/core/dev.c to here
- *	o Make Wireless Extension IOCTLs go through here
- *	o Added iw_handler handling ;-)
- *	o Added standard ioctl description
- *	o Initial dumb commit strategy based on orinoco.c
- *
- * v3 - 19.12.01 - Jean II
- *	o Make sure we don't go out of standard_ioctl[] in ioctl_standard_call
- *	o Add event dispatcher function
- *	o Add event description
- *	o Propagate events as rtnetlink IFLA_WIRELESS option
- *	o Generate event on selected SET requests
- *
- * v4 - 18.04.02 - Jean II
- *	o Fix stupid off by one in iw_ioctl_description : IW_ESSID_MAX_SIZE + 1
- *
- * v5 - 21.06.02 - Jean II
- *	o Add IW_PRIV_TYPE_ADDR in priv_type_size (+cleanup)
- *	o Reshuffle IW_HEADER_TYPE_XXX to map IW_PRIV_TYPE_XXX changes
- *	o Add IWEVCUSTOM for driver specific event/scanning token
- *	o Turn on WE_STRICT_WRITE by default + kernel warning
- *	o Fix WE_STRICT_WRITE in ioctl_export_private() (32 => iw_num)
- *	o Fix off-by-one in test (extra_size <= IFNAMSIZ)
- *
- * v6 - 9.01.03 - Jean II
- *	o Add common spy support : iw_handler_set_spy(), wireless_spy_update()
- *	o Add enhanced spy support : iw_handler_set_thrspy() and event.
- *	o Add WIRELESS_EXT version display in /proc/net/wireless
- *
- * v6 - 18.06.04 - Jean II
- *	o Change get_spydata() method for added safety
- *	o Remove spy #ifdef, they are always on -> cleaner code
- *	o Allow any size GET request if user specifies length > max
- *		and if request has IW_DESCR_FLAG_NOMAX flag or is SIOCGIWPRIV
- *	o Start migrating get_wireless_stats to struct iw_handler_def
- *	o Add wmb() in iw_handler_set_spy() for non-coherent archs/cpus
- * Based on patch from Pavel Roskin <proski@gnu.org> :
- *	o Fix kernel data leak to user space in private handler handling
- *
- * v7 - 18.3.05 - Jean II
- *	o Remove (struct iw_point *)->pointer from events and streams
- *	o Remove spy_offset from struct iw_handler_def
- *	o Start deprecating dev->get_wireless_stats, output a warning
- *	o If IW_QUAL_DBM is set, show dBm values in /proc/net/wireless
- *	o Don't lose INVALID/DBM flags when clearing UPDATED flags (iwstats)
- *
- * v8 - 17.02.06 - Jean II
- *	o RtNetlink requests support (SET/GET)
- *
- * v8b - 03.08.06 - Herbert Xu
- *	o Fix Wireless Event locking issues.
- *
- * v9 - 14.3.06 - Jean II
- *	o Change length in ESSID and NICK to strlen() instead of strlen()+1
- *	o Make standard_ioctl_num and standard_event_num unsigned
- *	o Remove (struct net_device *)->get_wireless_stats()
- *
- * v10 - 16.3.07 - Jean II
- *	o Prevent leaking of kernel space in stream on 64 bits.

+ * Call the commit handler in the driver

+ *
+ * Note : our current commit strategy is currently pretty dumb,

+ * The goal is to try to agreagate as many changes as possible
+ * before doing the commit. Drivers that will define a commit handler
+ * are usually those that need a reset after changing parameters, so
+ * we want to minimise the number of reset.
+ * A cool idea is to use a timer : at each "set" command, we re-set the
+ * timer, when the timer eventually fires, we call the driver.
+ * Hopefully, more on that later.
  *
- * IMPORTANT : This function prevent to set and get data on the same
- * IOCTL and enforce the SET/GET convention. Not doing it would be
- * far too hairy...
- * If you need to set and get data at the same time, please don't use
- * a iw_handler but process it in your ioctl handler (i.e. use the
- * old driver API).
+ * Also, I'm waiting to see how many people will complain about the

- * It needs to use those standard spy iw_handler in struct iw_handler_def,
- * push data to us via wireless_spy_update() and include struct iw_spy_data
- * in its private part (and export it in net_device->wireless_data->spy_data).
- * One of the main advantage of centralising spy support here is that
