Ask yourself *how* is the destructor invoked ? You can find *how* here: SKB
socket accounting <http://vger.kernel.org/%7Edavem/skb_sk.html>

So now if you run:
find . -name '*.c' | xargs grep -r -F "skb->destructor"

you will have what you are looking for :)

Hope this helps and this will help: http://vger.kernel.org/~davem/skb.html
