From 47a31a6ffcca3b55149bccd5b99763e5eea60ac4 Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Mon, 5 Nov 2007 23:39:16 -0800 Subject: [IPV4]: Use the {DEFINE|REF}_PROTO_INUSE infrastructure Trivial patch to make "tcp,udp,udplite,raw" protocols uses the fast "inuse sockets" infrastructure Each protocol use then a static percpu var, instead of a dynamic one. This saves some ram and some cpu cycles Signed-off-by: Eric Dumazet Signed-off-by: David S.
