From 1b37e0936815038a348230db69eaf00d2ecf4029 Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Sun, 15 Mar 2015 21:12:12 -0700 Subject: [PATCH] net: add sk_fullsock() helper We have many places where we want to check if a socket is not a timewait or request socket. Use a helper to avoid hard coding this. Signed-off-by: Eric Dumazet Signed-off-by: David S.
