From 3b7b2b0acdbf9ffe4d3a7915e59e6127988b05db Mon Sep 17 00:00:00 2001 From: David Ahern Date: Thu, 26 Jan 2017 14:08:36 -0800 Subject: [PATCH] net: ipv6: remove skb_reserve in getroute Remove skb_reserve and skb_reset_mac_header from inet6_rtm_getroute. The allocated skb is not passed through the routing engine (like it is for IPv4) and has not since the beginning of git time. Signed-off-by: David Ahern Acked-by: Eric Dumazet Signed-off-by: David S.
