+Sysfs
+~~~~~
+
+FUSE sets up the following hierarchy in sysfs:
+
+ /sys/fs/fuse/connections/N/
+
+where N is an increasing number allocated to each new connection.
+
+For each connection the following attributes are defined:
+
+ 'waiting'
+
+ The number of requests which are waiting to be transfered to
+ userspace or being processed by the filesystem daemon. If there is
+ no filesystem activity and 'waiting' is non-zero, then the
+ filesystem is hung or deadlocked.
+
+ 'abort'
+
+ Writing anything into this file will abort the filesystem
+ connection. This means that all waiting requests will be aborted an
+ error returned for all aborted and new requests.
+
+Only a privileged user may read or write these attributes.
+
+Aborting a filesystem connection
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+It is possible to get into certain situations where the filesystem is
+not responding. Reasons for this may be:
+
+ a) Broken userspace filesystem implementation
+
+ b) Network connection down
+
+ c) Accidental deadlock
+
+ d) Malicious deadlock
+
+(For more on c) and d) see later sections)
+
+In either of these cases it may be useful to abort the connection to
+the filesystem. There are several ways to do this:
+
+ - Kill the filesystem daemon. Works in case of a) and b)
+
+ - Kill the filesystem daemon and all users of the filesystem. Works
+ in all cases except some malicious deadlocks
+
+ - Use forced umount (umount -f). Works in all cases but only if
+ filesystem is still attached (it hasn't been lazy unmounted)
+
+ - Abort filesystem through the sysfs interface. Most powerful
+ method, always works.
+
How do non-privileged mounts work?

+Scenario 3 - Tricky deadlock with asynchronous read
+---------------------------------------------------
+
+The same situation as above, except thread-1 will wait on page lock
+and hence it will be uninterruptible as well. The solution is to
+abort the connection with forced umount (if mount is attached) or
+through the abort attribute in sysfs.

- It aims towards POSIX compliance.
+ Linux is a clone of the operating system Unix, written from scratch by
+ Linus Torvalds with assistance from a loosely-knit team of hackers across
+ the Net. It aims towards POSIX and Single UNIX Specification compliance.
- It has all the features you would expect in a modern fully-fledged
- Unix, including true multitasking, virtual memory, shared libraries,
- demand loading, shared copy-on-write executables, proper memory
- management and TCP/IP networking.
+ It has all the features you would expect in a modern fully-fledged Unix,
+ including true multitasking, virtual memory, shared libraries, demand
+ loading, shared copy-on-write executables, proper memory management,
+ and multistack networking including IPv4 and IPv6.
It is distributed under the GNU General Public License - see the
accompanying COPYING file for more details.
ON WHAT HARDWARE DOES IT RUN?
- Linux was first developed for 386/486-based PCs. These days it also
- runs on ARMs, DEC Alphas, SUN Sparcs, M68000 machines (like Atari and
- Amiga), MIPS and PowerPC, and others.
+ Although originally developed first for 32-bit x86-based PCs (386 or higher),
+ today Linux also runs on (at least) the Compaq Alpha AXP, Sun SPARC and
+ UltraSPARC, Motorola 68000, PowerPC, PowerPC64, ARM, Hitachi SuperH,
+ IBM S/390, MIPS, HP PA-RISC, Intel IA-64, DEC VAX, AMD x86-64, AXIS CRIS,
+ and Renesas M32R architectures.
+
+ Linux is easily portable to most general-purpose 32- or 64-bit architectures
+ as long as they have a paged memory management unit (PMMU) and a port of the
+ GNU C compiler (gcc) (part of The GNU Compiler Collection, GCC). Linux has
+ also been ported to a number of architectures without a PMMU, although
+ functionality is then obviously somewhat limited.

-/* OVERVIEW
- * --------
- *
- * The AMDTP driver is designed to expose the IEEE1394 bus as a
- * regular OSS soundcard, i.e. you can link /dev/dsp to /dev/amdtp and
- * then your favourite MP3 player, game or whatever sound program will
- * output to an IEEE1394 isochronous channel. The signal destination
- * could be a set of IEEE1394 loudspeakers (if and when such things
- * become available) or an amplifier with IEEE1394 input (like the
- * Sony STR-LSA1). The driver only handles the actual streaming, some
- * connection management is also required for this to actually work.
- * That is outside the scope of this driver, and furthermore it is not
- * really standardized yet.
- *
- * The Audio and Music Data Tranmission Protocol is available at
- *
- * http://www.1394ta.org/Download/Technology/Specifications/2001/AM20Final-jf2.pdf
- *
- *
- * TODO
- * ----
- *
- * - We should be able to change input sample format between LE/BE, as
- * we already shift the bytes around when we construct the iso
- * packets.
- *
- * - Fix DMA stop after bus reset!
- *
- * - Clean up iso context handling in ohci1394.
- *
- *
- * MAYBE TODO
- * ----------
- *
- * - Receive data for local playback or recording. Playback requires
- * soft syncing with the sound card.
- *
- * - Signal processing, i.e. receive packets, do some processing, and
- * transmit them again using the same packet structure and timestamps
- * offset by processing time.
- *
- * - Maybe make an ALSA interface, that is, create a file_ops
- * implementation that recognizes ALSA ioctls and uses defaults for
- * things that can't be controlled through ALSA (iso channel).
- *
- * Changes:
- *
- * - Audit copy_from_user in amdtp_write.
- * Daniele Bellucci <bellucda@tiscali.it>

-/* The userspace interface for the Audio & Music Data Transmission
- * Protocol driver is really simple. First, open /dev/amdtp, use the
- * ioctl to configure format, rate, dimension and either plug or
- * channel, then start writing samples.
- *
- * The formats supported by the driver are listed below.
- * AMDTP_FORMAT_RAW corresponds to the AM824 raw format, which can
- * carry any number of channels, so use this if you're streaming
- * multichannel audio. The AMDTP_FORMAT_IEC958_PCM corresponds to the
- * AM824 IEC958 encapsulation without the IEC958 data bit set, using
- * AMDTP_FORMAT_IEC958_AC3 will transmit the samples with the data bit
- * set, suitable for transmitting compressed AC-3 audio.
- *
- * The rate field specifies the transmission rate; supported values
- * are 32000, 44100, 48000, 88200, 96000, 176400 and 192000.
- *
- * The dimension field specifies the dimension of the signal, that is,
- * the number of audio channels. Only AMDTP_FORMAT_RAW supports
- * settings greater than 2.
- *
- * The mode field specifies which transmission mode to use. The AMDTP
- * specifies two different transmission modes: blocking and
- * non-blocking. The blocking transmission mode always send a fixed
- * number of samples, typically 8, 16 or 32. To exactly match the
- * transmission rate, the driver alternates between sending empty and
- * non-empty packets. In non-blocking mode, the driver transmits as
- * small packets as possible. For example, for a transmission rate of
- * 44100Hz, the driver should send 5 41/80 samples in every cycle, but
- * this is not possible so instead the driver alternates between
- * sending 5 and 6 samples.
- *
- * The last thing to specify is either the isochronous channel to use
- * or the output plug to connect to. If you know what channel the
- * destination device will listen on, you can specify the channel
- * directly and use the AMDTP_IOC_CHANNEL ioctl. However, if the
- * destination device chooses the channel and uses the IEC61883-1 plug
- * mechanism, you can specify an output plug to connect to. The
- * driver will pick up the channel number from the plug once the
- * destination device locks the output plug control register. In this
- * case set the plug field and use the AMDTP_IOC_PLUG ioctl.
- *
- * Having configured the interface, the driver now accepts writes of
- * regular 16 bit signed little endian samples, with the channels
- * interleaved. For example, 4 channels would look like:
- *
- * | sample 0 | sample 1 ...
- * | ch. 0 | ch. 1 | ch. 2 | ch. 3 | ch. 0 | ...
- * | lsb | msb | lsb | msb | lsb | msb | lsb | msb | lsb | msb | ...
