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. -- Thanks, Byungchul -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
