From 8295b6d9e623879344ed0ca7565336e4fd698e42 Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Mon, 5 Nov 2007 23:40:28 -0800 Subject: [SCTP]: Use the {DEFINE|REF}_PROTO_INUSE infrastructure Trivial patch to make "sctcp,sctpv6" 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.
