Subject: [IPV4]: Use the {DEFINE|REF}_PROTO_INUSE infrastructure
X-Git-Tag: v2.6.24-rc3~179^2~28
X-Git-Url: https://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=47a31a6ffcca3b55149bccd5b99763e5eea60ac4;p=pandora-kernel.git

[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
