This one might be a bad example.

There are 9 of them in net

[ I would think user space in general should be using inet_pton(3)  
everywhere for such interfaces, so the format of these addresses  
wouldn't matter so much.  Probably impossible at this point. ]

David Miller is authoritative here.

I'm not arguing one way or the other, but it would be useful if  
someone could check exactly what the dependencies are right now.  It  
seems like we're speculating a bit.
