Subject: CIFS: Fix wrong directory attributes after rename
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=4cf2ef68d23fcdea34b72325af7b9ac5f35f52ef;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

CIFS: Fix wrong directory attributes after rename

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.
