Hi Greg,
This backport series contains mostly fixes from v5.14 release along with one fix deferred from the first joint 5.10/5.15 series [1].
The upstream commit f8d92a66e810 ("xfs: prevent UAF in xfs_log_item_in_current_chkpt") was already applied to 5.15.y, but its 5.10.y backport was more involved (required two non trivial dependency patches), so it needed more time for review and testing.
Per Darrick's recommendation, on top of the usual regression tests, I also ran the "recoveryloop" tests group for an extended period of time to test for rare regressions.
Some recoveryloop tests were failing at rates less frequent than 1/100, but no change in failure rate was observed between baseline (v5.10.131) and the backport branch.
There was one exceptional test, xfs/455, that was reporting data corruptions after crash at very low rate - less frequent than 1/1000 on both baseline and backport branch.
It is hard to draw solid conclusions with such rare failures, but the test was run >10,000 times on baseline and >20,000 times on backport branch, so as far as our test coverage can attest, these backports are not introducing any obvious xfs regressions to 5.10.y.
Now queued up, thanks!
