Hi Pablo,

I have a scanned pdf of Linux kernel internals. But i stopped reading
when i found out struct sk_buff does not have a member struct
sk_buff_head * list like the book mentioned. It turns out its removed in
2.6.14/15 series where the book references a earlier code. 

On the plus side this made me set up cscope in my emacs. So i guess i
should thank the book for this.

Cheers.
