Folks, could somebody put together an xfstests (or LTP, for that matter)
patch adding that testcase?  Which regression suite is normally used
for NFS work, BTW?  It's not, strictly speaking, an NFS-specific bug
(you can trigger the same thing on AFS and CIFS as well), but NFS is
by far the most common of those three, so...
