After all the effort we've spent on this, I'm really, really happy to
see this (trying to) happen. Thanks for sending the patch. :-)

I fully agree with and second George's reasoning, and feel 100% like

Acked-by: Dario Faggioli <dfaggioli@xxxxxxxx>

Of course, although we thing the scheduler is ready, the more
testing/profiling/benchmarking/... we get, the better.

So, everyone, don't be shy at throwing any kind of things against it,
and report what happens, so we can fix the problem (or revert to
Credit!) for 4.12

Dario
