[patch 19/30] NET: Set truesize in pskb_copy

[Chris Wright]

-stable review patch.  If anyone has any objections, please let us know.
------------------

From: Herbert Xu <herbert@xxxxxxxxxxxxxxxxxxx>

Since pskb_copy tacks on the non-linear bits from the original
skb, it needs to count them in the truesize field of the new skb.
