 - Improve scalability of DM's device hash by switching to rbtree
 
 - Extend DM ioctl's DM_LIST_DEVICES_CMD handling to include UUID and
   allow filtering based on name or UUID prefix.
 
 - Various small fixes for typos, warnings, unused function, or
   needlessly exported interfaces.
 
 - Remove needless request_queue NULL pointer checks in DM thin and
   cache targets.
 
 - Remove unnecessary loop in DM core's __split_and_process_bio().
 
 - Remove DM core's dm_vcalloc() and just use kvcalloc or
   kvmalloc_array instead (depending whether zeroing is useful).
 
 - Fix request-based DM's double free of blk_mq_tag_set in device
   remove after table load fails.
 
 - Improve DM persistent data performance on non-x86 by fixing packed
   structs to have a stated alignment. Also remove needless extra work
   from redundant calls to sm_disk_get_nr_free() and a paranoid BUG_ON()
   that caused duplicate checksum calculation.
 
 - Fix missing goto in DM integrity's bitmap_flush_interval error
   handling.
 
 - Add "reset_recalculate" feature flag to DM integrity.
 
 - Improve DM integrity by leveraging discard support to avoid needless
   re-writing of metadata and also use discard support to improve
   hash recalculation.
 
 - Fix race with DM raid target's reshape and MD raid4/5/6 resync that
   resulted in inconsistant reshape state during table reloads.
 
 - Update DM raid target to temove unnecessary discard limits for raid0
   and raid10 now that MD has optimized discard handling for both raid
   levels.
