From 1d0ab253872cdd3d8e7913f59c266c7fd01771d0 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.
