I am not quite sure if the semantics that I baked into the code for this O_REGULAR flag's behavior when combined with other flags like O_CREAT look good and if there are other places that need the checks. I can fixup my patch according to suggestions for improvement. I did some happy path testing and the O_REGULAR flag seems to work as intended. Thanks.
