Merge branch 'for-linus' of git://git.kernel.dk/linux-2.6-block
* 'for-linus' of git://git.kernel.dk/linux-2.6-block:
compat_ioctl: fix block device compat ioctl regression
[BLOCK] Fix bad sharing of tag busy list on queues with shared tag maps
Fix a build error when BLOCK=n
block: use lock bitops for the tag map.
cciss: update copyright notices
cfq_get_queue: fix possible NULL pointer access
blk_sync_queue() should cancel request_queue->unplug_work
cfq_exit_queue() should cancel cfq_data->unplug_work
block layer: remove a unused argument of drive_stat_acct()
