  dm thin metadata: Fix use-after-free in dm_bm_set_read_only (2020-09-02 13:38:40 -0400)

Please pull, thanks!
Mike

----------------------------------------------------------------
- DM writecache fix to allow dax_direct_access() to partitioned pmem
  devices.

- DM multipath fix to avoid any Path Group initialization if
  'pg_init_in_progress' isn't set.

- DM crypt fix to use DECLARE_CRYPTO_WAIT() for onstack wait
  structures.

- DM integrity fix to properly check integrity after device creation
  when in bitmap mode.

- DM thinp and cache target __create_persistent_data_objects() fixes
  to reset the metadata's dm_block_manager pointer from PTR_ERR to
  NULL before returning from error path.

- DM persistent-data block manager fix to guard against
  dm_block_manager NULL pointer dereference in dm_bm_is_read_only()
  and update various opencoded bm->read_only checks to use
  dm_bm_is_read_only() instead.
