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.
