I mean if LL can do what you exactly did with "if" and no ABA problem can break the atomic_add_unless() users. Then no atomic_cmpxchg() users might be broken for the same reason. Why don't you put an "if" in the atomic_cmpxchg() to allow other users to have the same benefit because of the data? But this is out of the context for this patch. I actually don't have any API usage preference now.
