Thanks Andrew. Sorry for the trouble, I'll know to avoid this next time.

Not as well as the file backed path - it's not gotten real production use yet. However the plan is that this change will be in google's next kernel update, so it will get a lot more more testing soon (starting in ~1 week).
I did basic testing by dirtying an anon VMA larger that memory, then accessing it in random order while another thread runs a mmap/munmap loop, and checking that things behave as expected there (i.e. the patch allows the mmap/munmap thread to progress without waiting for the other thread swap-ins).
