What's the status on this series? I'm currently fleshing out an extension to
the atomic API that allows more flexible acquire/release semantics and it
doesn't make sense for me to copy-paste a bunch of code when I could build
it on top of this instead.

Also, do you have any other patches pending in this area? I've lost track...

Cheers,
