  dm: remove invalid sparse __acquires and __releases annotations (2020-12-04 15:25:18 -0500)

Please pull, thanks!
Mike

----------------------------------------------------------------
- Fix DM's bio splitting changes that were made during v5.9.
  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().
