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
