I checked back 6 months and this is only failing with rolling-upgrade-mds-zfs and rolling-downgrade-client1-zfs (old 2.12 client, new ZFS MDS) though I haven't looked at why that is the case. The first failure was 2023-03-24, but this was the first time that rolling upgrade was run, so I think the problem predates this time and is not related to a bad patch landing at that time. The failure is not hit with 2.14.0-2.15.x rolling-upgrade-mds-zfs testing, so it looks like the issue was introduced sometime in the 2.13 or 2.14 development cycle.
