Hi there! I'm happy to see this series has gotten renewed attention. The series was fine per se, and it even got through to the pu branch. But then it got ejected since it conflicted non-trivially with another patch series that was added along the way (see https://lwn.net/Articles/724166/). At that point I did not keep pushing it forward. I'd be happy to help anyone willing to make some progress on this! (Or even ultimately solve the conflict myself, if it serves a greater goal than just being a GSoC microproject.) Best, -- Daniel.
