PVF: does the kill_parent_node_in_emergency function still work?

I definitely tested it as non-root, but that was well before the unsharing stuff was introduced... I should re-test it and get rid of it if it's useless now.

I've done some tests and can confirm that kill_parent_node_in_emergency() works as expected. It is unaffected by namespace unsharing as the worker version check is performed before the unsharing takes place. The worker correctly determines the parent node's PID and sends SIGTERM to it; the node then exits gracefully (more or less) thanks to the global signal handler.

So, I believe I can close this issue for now.
