This function is a no-op if ns hierarchy is not mounted at this point.
This would mean that we will miss out on some directories in ns
hierarchy if it happened to be mounted later. It would be nice to
recreate such missing directories upon mount. However I suspect it would
not be easy ..Maybe we need to scan the task list and (re-)invoke
ns_container_clone() for every new tsk->nsproxy we find in the list.
Alternately perhaps we could auto mount (kern_mount) ns hierarchy very early at
bootup? On the flip side that would require remount support so that additional
controllers (like cpuset, mem) can be bound to (non-empty) ns hierarchy after
bootup.
