I have been reviewing it when I can, but this year I have been swamped
in other projects. Reviewing the atomic series is still my #1 priority
when I can.

I would hope it's not lack of interest, it's circumstances forcing
people to do other things. At least that's it for me.

Maybe another factor is that people are not comfortable reviewing
Weston patches.

I have already given an Ack for the overall design/architecture in the
atomic series, we just need the detailed review to check the code is

I believe the latest code is still
while the latest series with review comments is the v10 you can find

The last patch I reviewed so far was "[PATCH weston v10 21/61]
compositor-drm: Track all plane types", so review from that one onwards
would be nice. Mind the review comments given to the patches that are
marked as Changes Requested in Patchwork, I recall they still apply in
the v11-WIP branch.
