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@xxxxxxxxxx>
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.
