Keep in mind that those problems are generic, other filesystems also
suffer: http://www.spinics.net/lists/linux-mm/msg114123.html

I don't see any recent compaction-related patches in Linus' tree at
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/log/mm/

..so it seems they have not been merged yet.

So unless they get merged in the last minute it looks like 4.8 will
be DOA.
