The patch titled
CIFS: ignore mode change if it's just for clearing setuid/setgid bits
has been removed from the -mm tree. Its filename was
cifs-ignore-mode-change-if-its-just-for-clearing-setuid-setgid-bits.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: CIFS: ignore mode change if it's just for clearing setuid/setgid bits
From: Jeff Layton <jlayton@xxxxxxxxxx>
If the ATTR_KILL_S*ID bits are set then any mode change is only for clearing
the setuid/setgid bits. For CIFS, skip the mode change and let the server
handle it.
