I'll look for the 2nd > reviewer, and specify that in the next patch if found. If the xilinx activity gets too much we can always split things up again. But if it's just the occasional burst (around a new product for example), then drm-misc has ample of bandwidth to absorb that. And yes the idea is very much that all regular contributors would have commit rights too.
