Minor rant: the whole skb_alloc familly has degenerated into an unholy
mess and could use some rethinking.  I believe the current patch gets as
far as three _'s at the beginning of a function, this shows it is high
time to reroll the api.

I think it is merely an expression of how dynamic are the operations
that people want to perform on SKBs, and how important it is for
performance to implement COW semantics for the data.
