    OK. Because it can happen that I need to copy the skb for another
    reason (too little space for additional headers) I can just do
    something like

    if (skb_cloned(skb) || toosmall(skb)) {
    skn = skb_copy(skb, GFP_KERNEL);
    /* etc */
    }

    and this would be safe? Nice to know. :-)
