Calling "skb_cow_head" before we call "skb_clone" would indeed solve the problem of writes to our clones affecting clones in other parts of the system. But since we are still writing to the skb after "skb_clone", it'd still be better to replace "skb_clone" with "skb_copy" to avoid interference between our own clones.
