#     Merge tag 'for-5.10/dm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm
#     
#     Pull device mapper fixes from Mike Snitzer:
#     
#      - Fix DM's bio splitting changes that were made during v5.9. This
#        restores splitting in terms of varied per-target ti->max_io_len
#        rather than use block core's single stacked 'chunk_sectors' limit.
#     
#      - Like DM crypt, update DM integrity to not use crypto drivers that
#        have CRYPTO_ALG_ALLOCATES_MEMORY set.
#     
#      - Fix DM writecache target's argument parsing and status display.
#     
#      - Remove needless BUG() from dm writecache's persistent_memory_claim()
#     
#      - Remove old gcc workaround in DM cache target's block_div() for ARM
#        link errors now that gcc >= 4.9 is required.
#     
#      - Fix RCU locking in dm_blk_report_zones and dm_dax_zero_page_range.
#     
#      - Remove old, and now frowned upon, BUG_ON(in_interrupt()) in
#        dm_table_event().
#     
#      - Remove invalid sparse annotations from dm_prepare_ioctl() and
#        dm_unprepare_ioctl().
#     
#     * tag 'for-5.10/dm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm:
#       dm: remove invalid sparse __acquires and __releases annotations
#       dm: fix double RCU unlock in dm_dax_zero_page_range() error path
#       dm: fix IO splitting
#       dm writecache: remove BUG() and fail gracefully instead
#       dm table: Remove BUG_ON(in_interrupt())
#       dm: fix bug with RCU locking in dm_blk_report_zones
#       Revert "dm cache: fix arm link errors with inline"
#       dm writecache: fix the maximum number of arguments
#       dm writecache: advance the number of arguments when reporting max_age
#       dm integrity: don't use drivers that have CRYPTO_ALG_ALLOCATES_MEMORY
