That's not usually how these things work, unfortunately. Stuff going
into the merge window are those things that have been living in
linux-next for a while (usually since before the -rc5). Once Andrew is
done with the merge window for the -mm tree, he'll start scanning for
new things to pull in. I expect this to be one of them. :)
