Subject: [PATCH 4/4] NET : makes sctp use the {DEFINE|REF}_PROTO_INUSE infrastructure
Date: Mon, 05 Nov 2007 19:03:34 +0100 [thread overview]
Message-ID: <472F5AF6.1030208@cosmosbay.com> (raw)
[-- Attachment #1: Type: text/plain, Size: 259 bytes --]
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
