At least I would be happier without the patch. I'm trying to convince
people to not use these attributes unless required because too much
harm is done when they are used without understanding the full
consequences. I also recommend using __packed as localized as possible,
i.e. set it for the members that need it, not the entire struct.

I agree that your patch is harmless, it's just the opposite of
a cleanup in my opinion.
