Moved lru_cache.c to ~linux/lib lru_cache - documentation update, type cast removal Using kmalloc() first, trying vmalloc() as fallback for the page anchors of the bitmap Making everything kernel-doc compliant rename mdev->bc to mdev->ldev (to match the recent change to get_ldev/put_ldev) make drbd thread t_lock irqsave - lockdep complained, and lockdep is right (theoretically) Signed-off-by: Philipp Reisner <philipp.reisner@linbit.com> Signed-off-by: Lars Ellenberg <lars.ellenberg@linbit.com>

The variable virtio_blk references the function virtblk_probe() (which is in .devinit section) and also references the function virtblk_remove() ( which is in .devexit section). So, virtio_blk simultaneously refers .devinit and .devexit section. To avoid this messup, we mark virtio_blk as __refdata. We were warned by the following warning: LD drivers/block/built-in.o WARNING: drivers/block/built-in.o(.data+0xc8dc): Section mismatch in reference from the variable virtio_blk to the function .devinit.text:virtblk_probe() The variable virtio_blk references the function __devinit virtblk_probe() If the reference is valid then annotate the variable with __init* or __refdata (see linux/init.h) or name the variable: *driver, *_template, *_timer, *_sht, *_ops, *_probe, *_probe_one, *_console, WARNING: drivers/block/built-in.o(.data+0xc8e0): Section mismatch in reference from the variable virtio_blk to the function .devexit.text:virtblk_remove() The variable virtio_blk references the function __devexit virtblk_remove() If the reference is valid then annotate the variable with __exit* (see linux/init.h) or name the variable: *driver, *_template, *_timer, *_sht, *_ops, *_probe, *_probe_one, *_console, Signed-off-by: Rakib Mullick <rakib.mullick@gmail.com> Signed-off-by: Tejun Heo <tj@kernel.org>

2009-07-03cciss: Ignore stale commands after rebootHannes Reinecke
When doing an unexpected shutdown like kexec the cciss firmware might still have some commands in flight, which it is trying to complete. The driver is doing it's best on resetting the HBA, but sadly there's a firmware issue causing the firmware _not_ to abort or drop old commands. So the firmware will send us commands which we haven't accounted for, causing the driver to panic. With this patch we're just ignoring these commands as there is nothing we could be doing with them anyway.

For example, if you create a 2G object on an OSD device, you can then use this module to present that 2G object as a Linux block device. See inside patch for exact documentation.

2009-06-15debugfs: Fix terminology inconsistency of dir name to mount debugfs filesystem.GeunSik Lim
Many developers use "/debug/" or "/debugfs/" or "/sys/kernel/debug/" directory name to mount debugfs filesystem for ftrace according to ./Documentation/tracers/ftrace.txt file. And, three directory names(ex:/debug/, /debugfs/, /sys/kernel/debug/) is existed in kernel source like ftrace, DRM, Wireless, Documentation, Network[sky2]files to mount debugfs filesystem. debugfs means debug filesystem for debugging easy to use by greg kroah hartman. "/sys/kernel/debug/" name is suitable as directory name of debugfs filesystem. - debugfs related reference: http://lwn.net/Articles/334546/ Fix inconsistency of directory name to mount debugfs filesystem. * From Steven Rostedt - find_debugfs() and tracing_files() in this patch.

2009-06-15block/ps3: remove driver_data direct access of struct deviceRoel Kluin
In the near future, the driver core is going to not allow direct access to the driver_data pointer in struct device. Instead, the functions dev_get_drvdata() and dev_set_drvdata() should be used. These functions have been around since the beginning, so are backwards compatible with all older kernel versions.
