Hey, it's three weeks later and we're about to miss 5.2.

This sucks, Matthew. You introduced a serious regression to the MM
subsystem, whose process and patch routing you largely bypassed. When
I encountered the problem and provided a reproducer and a fix, you
gave me a hard time on cosmetic grounds. I incorporated all your
feedback, and still you show no urgency to get this patch or a fix of
your own into mainline. It's your bug, please fix it.
