Subject: [PATCH 3.2 052/125] nfsd: getattr for FATTR4_WORD0_FILES_AVAIL
 needs the statfs buffer

3.2.61-rc1 review patch.  If anyone has any objections, please let me know.

------------------

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

commit 12337901d654415d9f764b5f5ba50052e9700f37 upstream.

Note nobody's ever noticed because the typical client probably never
requests FILES_AVAIL without also requesting something else on the list.
