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.
