   4 Subject: CIFS: Fix wrong directory attributes after rename
   5

   8 commit b46799a8f28c43c5264ac8d8ffa28b311b557e03 upstream.
   9
  10 When we requests rename we also need to update attributes
  11 of both source and target parent directories. Not doing it
  12 causes generic/309 xfstest to fail on SMB2 mounts. Fix this
  13 by marking these directories for force revalidating.
