Correct, and since it's rc8 and I've just finished testing this, I
think I'll just wait till the merge window to push it to Linus. I'll be
putting it into linux-next until then.

You're too quick, I didn't think you were going to push it right
away ;-)

Yes, once the merge window opens (I'm guessing it may be this weekend?)
I'll submit it to Linus and after he pulls it, you can send your patch
to stable. I'll get notified when he does, and I can send you a poke to
let you know.
