sk_buff question

I need to had a header to the data in the sk_buff.
But what to do if there is no enough space left at the head ? I saw skb_copy_expand, but it gives me a new sk_buff. Is there a way to expand the headroom and keep the pointer on the sk_buff ?

Thanks

I assume "alloc+copy" isn't the expected answer, is it ?

pskb_expand_head maybe.
