Ok, so I take that's changes for CI runs, but not for patchwork
initiated tests.

Ok, so based on that this patchset is good to go I guess.

Still not sure why the test fails. One thing I noticed is a bunch of
"gem_concurrent: drop caches" messages in dmesg before any test would
be even started. So I think something in gem_concurrent is not guarded
with igt_fixture{} and gets to run when piglit enumerates the subtests
(to get the BAT subtests). Not sure though if this has a negative
effect on anything.
