Merge tag 'for-5.9/dm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm

Pull device mapper fixes from Mike Snitzer:

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

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

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

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

 - 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.

 - 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.
