Or just maybe because there are 1000+ posts on the list per month,
everyone is busy, and the commit message could be clearer about what the
tradeoff is to make the test faster?

If nobody responds within a week or two, please ping for reviews either
on the list or on freenode #intel-gfx IRC channel. Or both. Please don't
just silently wait and build up frustration/anger when it could simply
be that the patch slipped through the cracks.


BR,
Jani.
