Looking pretty good. I have one improvement.

I'd rather you pass the "kmem_cache_t" directly into sk_alloc, use
NULL for "I don't have any extra private area".

And then, for the IP case lay it out like this:

        struct sock
        struct ip_opt
        struct {tcp,raw4,...}_opt

And use different kmem_cache_t's for each protocol instead of
the same one for tcp, raw4, etc.

RAW/UDP sockets waste a lot of space with your current layout.
