Linus Torvalds 2f12d44085 - DM multipath locking fixes around m->flags tests and improvements to
bio-based code so that it follows patterns established by
   request-based code.
 
 - Request-based DM core improvement to eliminate unnecessary call to
   blk_mq_queue_stopped().
 
 - Add "panic_on_corruption" error handling mode to DM verity target.
 
 - DM bufio fix to to perform buffer cleanup from a workqueue rather
   than wait for IO in reclaim context from shrinker.
 
 - DM crypt improvement to optionally avoid async processing via
   workqueues for reads and/or writes -- via "no_read_workqueue" and
   "no_write_workqueue" features.  This more direct IO processing
   improves latency and throughput with faster storage.  Avoiding
   workqueue IO submission for writes (DM_CRYPT_NO_WRITE_WORKQUEUE) is
   a requirement for adding zoned block device support to DM crypt.
 
 - Add zoned block device support to DM crypt.  Makes use of
   DM_CRYPT_NO_WRITE_WORKQUEUE and a new optional feature
   (DM_CRYPT_WRITE_INLINE) that allows write completion to wait for
   encryption to complete.  This allows write ordering to be preserved,
   which is needed for zoned block devices.
 
 - Fix DM ebs target's check for REQ_OP_FLUSH.
 
 - Fix DM core's report zones support to not report more zones than
   were requested.
 
 - A few small compiler warning fixes.
 
 - DM dust improvements to return output directly to the user rather
   than require they scrape the system log for output.
