Oh crap, sorry. Quite the contrary. I should have waited for -rc1 as
this is intended for v3.10.

I made some major changes and wanted testing on it as soon as possible.
I've done tons of testing on my own but I wanted a broader audience. Do
you want me to pull my tree and reset it to what is only for 3.9?

All changes I wanted for 3.9 have already made it into Linus's tree.
Everything I've been pushing is destined for 3.10. But as I said. They
are big changes and wanted testing on them early. But it can wait for an
-rc1 window.
