Only PR in this batch related to this code path is: https://github.com/ceph/ceph/pull/33538

I don't see how #33538 would cause this.

The last run of kcephfs on Feb 16th did not have this issue: http://pulpito.ceph.com/pdonnell-2020-02-16_17:35:17-kcephfs-wip-pdonnell-testing-20200215.033325-distro-basic-smithi/
