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().
