I've stuck it in my locking/core branch for testing, I've had to fix a few minor rejects (my bad for being to slow), made a few minor edits and fixed that one masking thing. It seems to boot with the selftests all green, haven't done much else with it yet, we'll see. git://git.kernel.org/pub/scm/linux/kernel/git/peterz/queue.git locking/core Thanks!
