Linus Torvalds 48915c2cbc . various fixes and cleanups for request-based DM core 
. add support for delaying the requeue of requests; used by DM multipath
   when all paths have failed and 'queue_if_no_path' is enabled
 
 . DM cache improvements to speedup the loading metadata and the writing
   of the hint array
 
 . fix potential for a dm-crypt crash on device teardown
 
 . remove dm_bufio_cond_resched() and just using cond_resched()
 
 . change DM multipath to return a reservation conflict error
   immediately; rather than failing the path and retrying (potentially
   indefinitely)
