It's about 3 months too late for that. Ideally we want performance 
regressions to be looked for and reported when the patches go into the 
devel tree. Failing that, -rc1 would be the good time to re-test 
whatever workload you care about.

If you cannot test it in a regular fashion you can offload the testing 
to us, by adding a similar/equivalent workload to 'perf bench sched'. 
We'll make sure it stays sane.

Thanks,
