  dm: use op specific max_sectors when splitting abnormal io (2023-06-15
  12:47:16 -0400)

Please pull, thanks.
Mike

----------------------------------------------------------------
- Fix DM thinp discard performance regression introduced during 6.4
  merge; 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).
