Before I say "I agree and will clean up", Linus did it and the refined patch is already merged. Reading his patch, I am afraid there exists a possibitily of a problem. In creating a file (and in rcu-walk mode), if ->open returns ESTALE, then the problem may happen in the next ref-walk mode because intent.open.file is reset to NULL. But I don't know whether such ->open exists currently or not.
