Nadav is planning on doing a v4 of his patchset and it sounds like it will be significantly different.
So I'll await that patch series. Nadav, I think it would be best if you were to integrate Minchan's patchset on top of yours and maintain the whole set as a single series, please. That way it all gets tested at the same time and you're testing the hopefully-final result. If that's OK then please retain the various acks and reviewed-bys in the changelogs.
And we'll need to figure out which kernel versions to fix. Let's target 4.13-rcX for now, and assess the feasibility and desirability of backporting it all into -stable.
