[PATCH 3.13 078/198] nfsd: getattr for FATTR4_WORD0_FILES_AVAIL needs the statfs buffer

From: Kamal Mostafa
Date: Tue Jul 15 2014 - 17:34:24 EST


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

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

From: Christoph Hellwig <hch@xxxxxx>

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.
