I guess I'm confused about what kind of pre-merge testing we're talking
about then ... Or maybe this just doesn't work too well with the linux
kernel. The model is that you have some pile of trees, they're split up,
and testing of all the trees together is done in integration trees like
linux-next or drm-tip.

Criss-cross merging of trees just for integration testing is no-go. And
that seems to be the only reason you want drm-ci-next?

Also, this sounds more like msm being in a separate tree is the pain point
here, and solving "we have too many trees" by adding more isn't a good
idea ...

Or I'm just totally confused.
