PS1: 
I don't mind the change but I'm a bit reluctant to say that it's okay to look at size_out when the operation fails, because there are many different ways in which a CBFS access can fail and not all of them return a valid size. I guess if you just want to print it in an error message that's fine (make sure you zero-initialize it beforehand), but I don't think you should try anything more fancy with it.

I think you're not setting it in this path now.
