Basically, I absolutely hate the notion of us doing something unsynchronized, when I can see us undoing a mmap that another thread is doing. It's wrong.
You also didn't react to all the *other* things that were wrong in that patch-set. The games you play with !fatal_signal_pending() etc are just crazy.
End result: I absolutely detest the whole thing. I told you what I consider an acceptable solution instead, that is much simpler and doesn't have any of the problems of your patchset.
