Subject: [GIT PULL] iomap: fixes for 5.17-rc3
Date: Fri, 4 Feb 2022 18:46:13 -0800	[thread overview]
Message-ID: <20220205024613.GV8313@magnolia> (raw)

Hi Linus,

Please pull this branch containing a single bugfix for iomap for
5.17-rc3.  The fix should eliminate occasional complaints about stall
warnings when a lot of writeback IO completes all at once and we have to
then go clearing status on a large number of folios.

As usual, I did a test-merge with upstream master as of a few minutes
ago, and didn't see any conflicts.  Please let me know if you encounter
any problems.

  xfs, iomap: limit individual ioend chain lengths in writeback (2022-01-26 09:19:20 -0800)

Fixes for 5.17-rc2:
 - Limit the length of ioend chains in writeback so that we don't trip
   the softlockup watchdog and to limit long tail latency on clearing
