Yes, agree. I should've said 'Lockdep doesn't detect it currently.' rather than 'Lockdep can't detect it.'.
I also think we make it for this case by fixing the bug in Lockdep.
That's why I said Lockdep cannot detect it. By any chance, has it changed so as to consider this case? Or am I missing something?
