Cover letter [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,
