Sorry, the list is not accessed outside, plus, you have to run some
commands to generate the list on fly. Anyway, I checked it for you,
and we have run hackbench/performance-50%-threads-socket only on that
commit, which is reasonable in our system as we bisected once on this
issue.

But I can run more tests(say, with 100% and 1600% cpu) on that commit if
you like, and it also would be good if you can name some of benchmarks
you care most so that we can run it for you.
