The patch does nothing of the sort. Not unless there is a bug I am not
seeing anyway. It does assume nobody tries to grab pairs of such
resources as it doesn't do deadlock avoidance.

It's now a shared resource patch however, its a multiplexor patch and
that is precisely why it is called MUX not SHARED or OVERLAY
