From 6892286e9c09925780fe2cb6db3585b56b71fe8e Mon Sep 17 00:00:00 2001 From: David Miller Date: Mon, 11 Jun 2018 18:00:13 -0700 Subject: [PATCH] tcp: Do not reload skb pointer after skb_gro_receive(). This is not necessary. skb_gro_receive() will never change what 'head' points to. In it's original implementation (see commit 71d93b39e52e ("net: Add skb_gro_receive")), it did: ==================== + *head = nskb; + nskb->next = p->next; + p->next = NULL; ==================== This sequence was removed in commit 58025e46ea2d ("net: gro: remove obsolete code from skb_gro_receive()") Signed-off-by: David S.
