Description

During Yuri's nautilus backport test run, hit the following failure error in multimds suite's xfs tests running in Ubuntu xenial environment with FUSE clients.

Yuri ran the multimds suite twice. Both the times observed the above issue only in ubuntu xenial environments.

Interesting that it was reproducible for two runs. We've not seen this before but I'm suspicious that it probably exists on master too.
