Subject: [PATCH 5.15 120/196] cifs: fix set of group SID via NTSD xattrs

From: Amir Goldstein <amir73il@...il.com>

commit dd5a927e411836eaef44eb9b00fece615e82e242 upstream.

'setcifsacl -g <SID>' silently fails to set the group SID on server.

Actually, the bug existed since commit 438471b67963 ("CIFS: Add support
for setting owner info, dos attributes, and create time"), but this fix
will not apply cleanly to kernel versions <= v5.10.

Fixes: 3970acf7ddb9 ("SMB3: Add support for getting and setting SACLs")
Cc: stable@...r.kernel.org # 5.11+
