    Merge tag 'for-5.9/dm-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm
    
    Pull device mapper updates from Mike Snitzer:
    
     - 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.
