The patch titled
NFS: if ATTR_KILL_S*ID bits are set, then skip mode change
has been removed from the -mm tree. Its filename was
nfs-if-attr_kill_sid-bits-are-set-then-skip-mode-change.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: NFS: if ATTR_KILL_S*ID bits are set, then skip mode change
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 NFS, skip the mode change and let the server
handle it.
