I applied the patch on a recent snapshot, recompiled the kernel and
can no longer reproduce the issue.  NFS operations appear to work fine
and I cannot reproduce the issue even after restarting nfsd multiple
times.  FWIW, I uncovered this issue after updating a system to
4.7--4.6 did not have this issue.

Thank you Mark.
