Which ever is easier ;-)

I just hated the magic "1" and "2". As long as I (or any reviewer) does
not need to go searching for numbers, and can easily figure out what is
going on by looking at the code at hand, I'm happy.

Both the above satisfy that requirement.

Your "is_ret_probe(tu)" may have the added bonus of being less error
prone.

Thanks,
