Ok, makes sense to me now. Indeed this makes the patch wrong :)

Are you annoyed if I integrate this in -next ? I want to release -rc1
today, and I think this kind of stuff is a little bit too sensitive to
be merged now. From your quick feedback on those patches, I have the
feeling that you wanted it in 2013.08, so I don't want to ruin your
hope, but I believe it's a bit too late now. What do you think?
