2010-11-06floppy: fix another use-after-freeVivek Goyal
While scanning the floopy code due to c093ee4f07f4 ("floppy: fix use-after-free in module load failure path"), I found one more instance of trying to access disk->queue pointer after doing put_disk() on gendisk. For some reason , floppy moule still loads/unloads fine. The object is probably still around with right pointer values. o There seems to be one more instance of trying to cleanup the request queue after we have called put_disk() on associated gendisk. o This fix is more out of code inspection. Even without this fix for some reason I am able to load/unload floppy module without any issues. o Floppy module loads/unloads fine after the fix.

2010-11-06floppy: fix use-after-free in module load failure pathLinus Torvalds
Commit 488211844e0c ("floppy: switch to one queue per drive instead of sharing a queue") introduced a use-after-free. We do "put_disk()" on the disk device _before_ we then clean up the queue associated with that disk. Move the put_disk() down to avoid dereferencing a free'd data structure.

Fix up trivial conflict in drivers/block/ataflop.c due to BKL removal
2010-10-05block: autoconvert trivial BKL users to private mutexArnd Bergmann
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>
2010-09-22floppy: switch to one queue per drive instead of sharing a queueJens Axboe
Pretty straight forward conversion. Note that we do round-robin between the drives that have available requests, before we simply used the drive that the IO scheduler told us to. Since the IO scheduler doesn't care about multiple devices per queue, the resulting sort would not have made sense.

2010-08-07block: push down BKL into .open and .releaseArnd Bergmann
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.

2010-08-07block: push down BKL into .locked_ioctlArnd Bergmann
