Perhaps that should have read s/testing//? I think all he's looking
for is a "yes" from each driver team with changes in stable. This can
be derived from your supreme confidence in your mesa-stable tagging
(and Carl's super-human cherry-picking), or just seeing if the thing
builds with your driver, or actually running it on any hw you deem
necessary.

FTR, I believe I'm the one who suggested adding teeth to this since I
felt that no one would actually do any checking unless there was some
reason to. The mesa/core and mesa/st changes get a free ride since (a)
Carl can test them on his setup via soft/llvmpipe and (b) the shared
responsibility makes it awkward.

Cheers,
