I'm happy to put v2 in linux-next now (only patch 4 has changed, I just
sent an updated version), and send you a pull request early next week so
you can take it from there. The patches can't be directly applied with
git-am anyway thanks to the -D option to make them more concise.

Sound okay?

James
