Thanks a lot for working on this. I'll review this patch a bit later,
but let me post links to patches on which we had some earlier
discussions, to keep things together:

https://patchwork.kernel.org/patch/10462311/
https://patchwork.kernel.org/patch/10577969/

Also CCd folks who discussed there.

Best regards,
