Subject: [RFC patch 0/2] posix mqueue namespace (v12)

Posix message queue support in ipc namespaces has had
several submissions by various people.  Hopefully this
version, based on code by both Cedric Le Goater and
Nadia Derbey has a shot at making it upstream.

To create a new ipc namespace with posix mq support, you
would

	unshare(CLONE_NEWIPC|CLONE_NEWNS);
	umount /dev/mqueue
	mount -t mqueue mqueue /dev/mqueue

It's perfectly valid to do vfs operations on files
in another ipc_namespace's /dev/mqueue, but any use
of mq_open(3) and friends will act in your own ipc_ns.

thanks,
