Bug description:
[Impact]
* Umounts to OCFS2 filesystems will cause a kernel crash in any
kernel containing commit e581595ea29c (v5.3-rc1) and not containing
its fix b73eba2a867e (v5.5-rc5).
[Test Case]
* ocfs2_reproducer.sh (attached to this bug)
[Regression Potential]
* it could cause ocfs2 issues, so I guess its a low impact considering
amount of users.
* Its a straightforward fix identified by upstream developer and a clean
cherry-pick for us.
[Other Info]
* Original description:
I noticed the tests for ocfs2-tools/1.8.6-1ubuntu1 were constantly
retrying themselves. It's a feature we have so that transient /
occasional failures are auto-retried, but it's misfiring here because
we're not detecting that it's a consistent failure. That particular
bug is fixed, but it means that ocfs2-tools is failing on ppc64el.
Here's the important part of the log, full output attached.
