From: Trond Myklebust <trond.myklebust@xxxxxxxxxxxxxxx>
This patch has been added to the 4.1 stable tree. If you have any
objections, please let us know.
===============
[ Upstream commit cd812599796f500b042f5464b6665755eca21137 ]
Setting the change attribute has been mandatory for all NFS versions, since
commit 3a1556e8662c ("NFSv2/v3: Simulate the change attribute"). We should
therefore not have anything be conditional on it being set/unset.
