Side note: I also think the thing is just broken.
Any actual cross-releaser should be way more annotated than just "set
cross to 1" in the lockdep map.
The place where the release is done should simply be special.
Because we should *not* encourage the whole "acquire by one context,
release by another" as being something normal and "just set the flag
to let lockdep know".
So that commit is apparently buggy, but I think it might be more
fundamentally the wrong model too.
