The patch titled
ecryptfs: allow lower fs to interpret ATTR_KILL_S*ID
has been removed from the -mm tree. Its filename was
ecryptfs-allow-lower-fs-to-interpret-attr_kill_sid.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: ecryptfs: allow lower fs to interpret ATTR_KILL_S*ID
From: Jeff Layton <jlayton@xxxxxxxxxx>
Make sure ecryptfs doesn't trip the BUG() in notify_change. This also allows
the lower filesystem to interpret ATTR_KILL_S*ID in its own way.
