Could you please elaborate?
it seems to me skb_realloc_headroom used before my patch called pskb_expand_head() too
and did not adjusted skb->truesize too. Am I missed something perhaps?

The only difference in my patch is that skb_clone can be not called,
though I do not understand how this can affect skb->truesize.

Thank you,
Vasily Averin
