Merge tag 'iomap-5.17-fixes-1' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux
Pull iomap fix from Darrick Wong:
"A single bugfix for iomap.
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.
Summary:
- 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
PageWriteback"
* tag 'iomap-5.17-fixes-1' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux:
xfs, iomap: limit individual ioend chain lengths in writeback
