Subject: [PATCH 3.12 58/66] nfsd: correctly define v4.2 support attributes

From: Christoph Hellwig <hch@....de>

3.12-stable review patch.  If anyone has any objections, please let me know.

===============

commit 6d0ba0432a5e10bc714ba9c5adc460e726e5fbb4 upstream.

Even when security labels are disabled we support at least the same
attributes as v4.1.
