Just a heads up that sparse gives some warnings with these patches:

drivers/md/dm.c:689:24: warning: context imbalance in 'dm_get_live_table_fast' - wrong count at exit
drivers/md/dm.c:695:13: warning: context imbalance in 'dm_put_live_table_fast' - unexpected unlock
drivers/md/dm.c:1789:17: warning: context imbalance in 'dm_request_fn' - unexpected unlock
