From: Eric Dumazet <edumazet@google.com> __skb_splice_bits() can check if skb to be spliced has its skb->head mapped to a page fragment, instead of a kmalloc() area. If so we can avoid a copy of the skb head and get a reference on underlying page. Signed-off-by: Eric Dumazet <edumazet@google.com>
Applied.
