The patch titled
unionfs: fix unionfs_setattr to handle ATTR_KILL_S*ID
has been removed from the -mm tree. Its filename was

------------------------------------------------------
Subject: unionfs: fix unionfs_setattr to handle ATTR_KILL_S*ID
From: Jeff Layton <[EMAIL PROTECTED]>
Don't allow unionfs_setattr to trip the BUG() in notify_change. Clear
ATTR_MODE if the either ATTR_KILL_S*ID is set. This also allows the
lower filesystem to interpret these bits in its own way.
