I apologize to all of you. That's really not what I intended to say.

I said that other folks can annotate it for the sub-system better
than lockdep developer, so suggested to invalidate locks making
trouble and wanting to avoid annotating it at the moment, and
validate those back when necessary with additional annotations.

It's my fault. I'm not sure how I should express what I want to say,
but, I didn't intend to charge the responsibility to other folks.

Ideally, I think it's best to solve it with co-work. I should've been
more careful to say that.

Again, I apologize for that, to lockdep and fs maintainers.

Of course, for cross-release, I have the will to annotate it or
find a better way to avoid false positives. And I think I have to.
