Okay, so here it is. It fixes the issue for me and doesn't cause any
lockdep splats on my machine. I am not sure how far this needs to be
backported via stable, so I didn't specify it. Same with a Fixes tag.
Oh, and I added your comment :-) (which makes up most of the added
lines, so feel free to change authorship to you).
