this op is only intended to be used only by the lock debugging
infrastructure. So it should be renamed - but i fail to find a good name
for it. (it's used quite frequently within the lock debugging code, at
60+ places) Maybe INTERNAL_WARN_ON()? [that makes it sound special
enough.] DEBUG_LOCKS_WARN_ON() might work too.
