I totally agree with you. *They aren't really locks but it's just waits

interested in locks unlike Lockdep, but fouces on waits and wakeup
sources itself. I think you get Dept wrong a lot. Please ask me more if
you have things you doubt about Dept.

So the question is this --- do you now understand why, even though
there is a circular dependency, nothing gets stalled in the
interactions between the two wait channels?
