While I would say two argument form would have been better if this were a new code, this change is borderline Meh for existing code, because passing 0 there already gives a reasonable sign that we know this parameter does not matter. If the ignored parameter were 0666 or some other more plausible-as-perm-bits value, the story would be quite different, though. Thanks.
