sorry, I'm going to check more thoroughly next time.

Also, I think you might have missed one of my cleanup patches:
https://patchwork.kernel.org/patch/6275111/

At least I haven't seen it yet in for-next or fixes.

And if you could say a few words about the layer rework series

would be great! :)



With best wishes,
