Oops, I noticed that Chen Yu sent a new version of his patches on
July 2017:

https://patchwork.kernel.org/patch/9861179/
https://patchwork.kernel.org/patch/9861175/
https://patchwork.kernel.org/patch/9861173/
https://patchwork.kernel.org/patch/9861177/

I will send a V3 using this series instead of the old RFC one:
https://patchwork.kernel.org/patch/6402801/

Sorry about the noise.
