2010-10-05	block: autoconvert trivial BKL users to private mutex	Arnd Bergmann	1	-3/+4
	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.<linux\/smp_lock.h>/d' ${file} else sed -i 's/include.<linux\/smp_lock.h>.$/include <linux\/mutex.h>/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.*\<smp_lock.h\>/d' ${file} \ -e '/cycle_kernel_lock()/d' fi Signed-off-by: Arnd Bergmann <arnd@arndb.de>
2010-08-07	block: push down BKL into .locked_ioctl	Arnd Bergmann	1	-2/+7
	As a preparation for the removal of the big kernel lock in the block layer, this removes the BKL from the common ioctl handling code, moving it into every single driver still using it.

2008-10-17	ide: add generic ATA/ATAPI disk driver	Bartlomiej Zolnierkiewicz	1	-3/+1
	* Add struct ide_disk_ops containing protocol specific methods. * Add 'struct ide_disk_ops ' to ide_drive_t. Convert ide-{disk,floppy} drivers to use struct ide_disk_ops. * Merge ide-{disk,floppy} drivers into generic ide-gd driver. While at it: - ide_disk_init_capacity() -> ide_disk_get_capacity() Acked-by: Borislav Petkov <petkovbb@gmail.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
