Subject: [dm-devel] [git pull] device mapper fixes for 6.4-rc7

Hi Linus,
The following changes since commit f1fcbaa18b28dec10281551dfe6ed3a3ed80e3d6:
Linux 6.4-rc2 (2023-05-14 12:51:40 -0700)

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).
