What is the new lock protecting against? You no longer have a mutual
exclusion with the other code, which looks like it is a functional
change, and also incorrect.
It also sounds like the code was broken after the first patch and
you need this one to make it compile again. You can't do that, and
instead need to change the locking rules first.
Oh, that's right! Sorry I will take a look again.
