drivers/memstick: Add module.h to the prev. implicit modular users

2011-10-31T23:31:52Z

This is another group of drivers that simply assumed that module.h was everywhere. But it won't be once we clean up its presence from device.h Call out the real users of it in advance. Signed-off-by: Paul Gortmaker

memstick: change to new flag variable

2011-03-17T13:05:34Z

The EXTRA_CFLAGS assignment in memstick/Makefile was not accomplishing anything because this flag only has effect on sources at the same level as the makefile (i.e., per directory). Since both core/ and host/ rely on MEMSTICK_DEBUG, the subdir-ccflags-y variant seems to be the appropriate choice. Signed-off-by: matt mooney Acked-by: WANG Cong Signed-off-by: Michal Marek

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
