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).

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).

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
