[akpm]

The patch titled
     pid namespaces: allow signalling cgroup-init
has been removed from the -mm tree.  Its filename was
     pid-namespaces-allow-signalling-container-init.patch

This patch was dropped because it was merged into mainline or a subsystem tree

------------------------------------------------------
Subject: pid namespaces: allow signalling cgroup-init
From: Sukadev Bhattiprolu <sukadev@us.ibm.com>

Only the global-init process must be special - any other cgroup-init
process must be killable to prevent run-away processes in the system.

TODO: 	Ideally we should allow killing the cgroup-init only from parent
	cgroup and prevent it being killed from within the cgroup.
	But that is a more complex change and will be addressed by a follow-on
	patch. For now allow the cgroup-init to be terminated by any process
	with sufficient privileges.
