I was going to test this, since the previous version failed for me.
But it's based on linux-next, and I didn't want to fight the conflicts
(including - but not limited to - the header file being moved) so I
dropped that plan.

If you think it's worth testing on the setup that used to fail, and
you send me a version that applies on my current tree, I can do so.
