Hello,
recently I've debugged a deadlock issue in ext4 fast commit feature in our openSUSE Leap kernel. Checking with upstream I've found out the issue was accidentally fixed by commit 2729cfdcfa1c ("ext4: use ext4_journal_start/stop for fast commit transactions"). Can you please pick up this commit into the stable tree? The problem has been there since fast commit began to exist (in 5.10-rc1) so 5.10 and 5.15 stable trees need the fix. Thanks!
This commit does not apply to those branches, so how was it tested?
Hum, I've picked up the patch to our 5.14-based distro kernel and it applied (and passed testing) without issues so I was hoping 5.15 and 5.10 would work as well. Apparently I was wrong. Sorry for the trouble.
Can you send us backported, and tested, versions of this commit so that we can apply them?
Yeah, I'll look into applying the patch directly to stable branches.
