From: Eric Dumazet Date: Tue, 6 Nov 2007 07:40:28 +0000 (-0800) Subject: [SCTP]: Use the {DEFINE|REF}_PROTO_INUSE infrastructure X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=8295b6d9e623879344ed0ca7565336e4fd698e42;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git [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.
