Subject: [PATCH 3.13 010/163] CIFS: Fix wrong restart readdir for SMB1

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

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

From: Pavel Shilovsky <pshilovsky@...ba.org>

commit f736906a7669a77cf8cabdcbcf1dc8cb694e12ef upstream.

The existing code calls server->ops->close() that is not
right. This causes XFS test generic/310 to fail. Fix this
by using server->ops->closedir() function.
