Merge tag 'for-6.4/dm-fixes' of git://git./linux/kernel/git/device-mapper/linux-dm

Pull device mapper fixes from Mike Snitzer:

 - Fix DM thinp discard performance regression introduced during this
   merge window where DM core was splitting large discards every 128K
   (max_sectors_kb) rather than every 64M (discard_max_bytes).

 - Extend DM core LOCKFS fix, made during 6.4 merge, to also fix race
   between do_mount and dm's do_suspend (in addition to the earlier
   fix's do_mount race with dm's do_resume).

 - Fix DM thin metadata operations to first check if the thin-pool is in
   "fail_io" mode; otherwise UAF can occur.

 - Fix DM thinp's call to __blkdev_issue_discard to use GFP_NOIO rather
   than GFP_NOWAIT (__blkdev_issue_discard cannot handle NULL return
   from bio_alloc).

  dm: use op specific max_sectors when splitting abnormal io
  dm thin: fix issue_discard to pass GFP_NOIO to __blkdev_issue_discard
  dm thin metadata: check fail_io before using data_sm
  dm: don't lock fs when the map is NULL during suspend or resume
