[PATCH 3.14 101/114] CIFS: Fix wrong directory attributes after rename

From: Greg Kroah-Hartman
Date: Mon Sep 15 2014 - 15:47:09 EST


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

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

From: Pavel Shilovsky <pshilovsky@xxxxxxxxx>

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.
