Thanks. I've queued a reversion patch. I'll hold off sending it to
Linus for a while, to see if we can get this fixed up.

What does "hang" mean? Was the machine all locked up? Or is it the
case that the particular LTP test failed to complete? I suspect the
latter - that the new notify behaviour is differing from LTP's
expectation in some fashion?
