Hmm, right. I didn't notice the new call site added by one series when
rebasing the other series :/

I think the easiest thing to do for now is to drop from mmotm:
mm-compaction-direct-freepage-allocation-for-async-direct-compaction.patch
As Mel and Joonsoo didn't like it in the current state anyway.

That leaves just this part, which didn't fit anywhere else. I guess can
just fold it to upcoming kcompactd patches?
Thanks for organizing my morning today, Hugh :)
