Ugh. I'm adding PeterZ to the cc, just to see if he can make more sense of it.

Peter, is there no way to make the lock thing print not just the lock
class name, but also the pointer to the actual *instance* of the lock
held?

Also, it's a bit unclear to me, but I *think* that most of those users
don't actually "hold" the lock - they are waiting for it. Yes/no? Does
the lockdep information have the capability to distinguish between
"waiting for" vs "actually successfully owns the lock"?
