Hi Bryan

Often you know some thing has been done, because if it had not been
done, you would of bombed out with an error. In the release function
you can assume everything done in probe has been done, otherwise the
probe would not be successful. In close, you can assume everything
done in open was successful, otherwise the open would of failed....

So probe does not need any flags. open does not need any flags.
