Subject: [PATCH 3.13 019/103] CIFS: Fix wrong directory attributes after rename

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

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

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

commit b46799a8f28c43c5264ac8d8ffa28b311b557e03 upstream.

When we requests rename we also need to update attributes
of both source and target parent directories. Not doing it
causes generic/309 xfstest to fail on SMB2 mounts. Fix this
by marking these directories for force revalidating.
