#     Merge tag 'for-5.19/dm-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm
#     
#     Pull device mapper updates from Mike Snitzer:
#     
#      - Enable DM core bioset's per-cpu bio cache if QUEUE_FLAG_POLL set.
#        This change improves DM's hipri bio polling (REQ_POLLED) performance
#        by 7 - 20% depending on the system.
#     
#      - Update DM core to use jump_labels to further reduce cost of unlikely
#        branches for zoned block devices, dm-stats and swap_bios throttling.
#     
#      - Various DM core changes to reduce bio-based DM overhead and simplify
#        IO accounting.
#     
#      - Fundamental DM core improvements to dm_io reference counting and the
#        elimination of using bio_split()+bio_chain() -- instead DM's
#        bio-based IO accounting is updated to account that a split occurred.
#     
#      - Improve DM core's abnormal bio processing to do less work.
#     
#      - Improve DM core's hipri polling support to use a single list rather
#        than an hlist.
#     
#      - Update DM core to pass NULL bdev to bio_alloc_clone() so that
#        initialization that isn't useful for DM can be elided.
#     
#      - Add cond_resched to DM stats' various loops that loop over all
#        entries.
#     
#      - Fix incorrect error code return from DM integrity's constructor.
#     
#      - Make DM crypt's printing of the key constant-time.
#     
#      - Update bio-based DM multipath to provide high-resolution timer to the
#        Historical Service Time (HST) path selector.
#

#       dm: use bio_sectors in dm_aceept_partial_bio
#       dm: simplify basic targets
#       dm: conditionally enable branching for less used features
