workqueue, freezer: unify spelling of 'freeze' + 'able' to 'freezable'

2011-02-16T16:48:59Z

There are two spellings in use for 'freeze' + 'able' - 'freezable' and 'freezeable'. The former is the more prominent one. The latter is mostly used by workqueue and in a few other odd places. Unify the spelling to 'freezable'. Signed-off-by: Tejun Heo Reported-by: Alan Stern Acked-by: "Rafael J.

memstick: factor out transfer initiating functionality in mspro_block.c

2011-01-13T16:03:22Z

Apart from currently used standard memstick data transfer method, Sony introduced several newer ones, to uncover full bandwidth/capacity of its Pro, HG and XC media formats. This patch lays a foundation to enable those methods as made possible by host/media capabilities. As a side effect of this patch, mspro_block_read_attributes became more streamlined and readable.

memstick: remove mspro_block_mutex

2011-01-13T16:03:22Z

mspro_block_mutex is identical in scope to mspro_block_disk_lock and therefore unnecessary. Signed-off-by: Alex Dubov Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

memstick: avert possible race condition between idr_pre_get and idr_get_new

2011-01-13T16:03:22Z

Implement the usual pattern around idr_pre_get() and idr_get_new() to handlethe situation where another thread concurrently steals this thread's idr_pre_get() preallocation. Signed-off-by: Alex Dubov Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

memstick: core: fix device_register() error handling

2011-01-13T16:03:21Z

If device_register() fails then call put_device(). See comment to device_register. Signed-off-by: Vasiliy Kulikov Cc: Maxim Levitsky Cc: Alex Dubov Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

block: autoconvert trivial BKL users to private mutex

2010-10-05T13:01:10Z

The block device drivers have all gained new lock_kernel calls from a recent pushdown, and some of the drivers were already using the BKL before. This turns the BKL into a set of per-driver mutexes. Still need to check whether this is safe to do. file=$1 name=$2 if grep -q lock_kernel ${file} ; then if grep -q 'include.*linux.mutex.h' ${file} ; then sed -i '/include.*/d' ${file} else sed -i 's/include.*.*$/include /g' ${file} fi sed -i ${file} \ -e "/^#include.*linux.mutex.h/,$ { 1,/^$static\|int\|long$/ { /^$static\|int\|long$/istatic DEFINE_MUTEX(${name}_mutex); } }" \ -e "s/$un$*lock_kernel\>[ ]*()/mutex_\1lock(\&${name}_mutex)/g" \ -e '/[ ]*cycle_kernel_lock();/d' else sed -i -e '/include.*\/d' ${file} \ -e '/cycle_kernel_lock()/d' fi Signed-off-by: Arnd Bergmann

memstick: fix hangs on unexpected device removal in mspro_blk

2010-08-12T15:43:31Z

mspro_block_remove() is called from detect thread that first calls the mspro_block_stop(), which stops the request queue. If we call del_gendisk() with the queue stopped we get a deadlock. Signed-off-by: Maxim Levitsky Cc: Alex Dubov Cc: Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

block: push down BKL into .open and .release

2010-08-07T16:25:34Z

The open and release block_device_operations are currently called with the BKL held. In order to change that, we must first make sure that all drivers that currently rely on this have no regressions. This blindly pushes the BKL into all .open and .release operations for all block drivers to prepare for the next step. The drivers can subsequently replace the BKL with their own locks or remove it completely when it can be shown that it is not needed. The functions blkdev_get and blkdev_put are the only remaining users of the big kernel lock in the block layer, besides a few uses in the ioctl code, none of which need to serialize with blkdev_{get,put}. Most of these two functions is also under the protection of bdev->bd_mutex, including the actual calls to ->open and ->release, and the common code does not access any global data structures that need the BKL.

block: remove wrappers for request type/flags

2010-08-07T16:17:56Z

Remove all the trivial wrappers for the cmd_type and cmd_flags fields in struct requests. This allows much easier grepping for different request types instead of unwinding through macros. Signed-off-by: Christoph Hellwig Signed-off-by: Jens Axboe
