From 65f7651788e18fadb2fbb7276af935d7871e1803 Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Thu, 3 Jan 2008 20:46:48 -0800 Subject: [NET]: prot_inuse cleanups and optimizations 1) Cleanups (all functions are prefixed by sock_prot_inuse) sock_prot_inc_use(prot) -> sock_prot_inuse_add(prot,-1) sock_prot_dec_use(prot) -> sock_prot_inuse_add(prot,-1) sock_prot_inuse() -> sock_prot_inuse_get() New functions : sock_prot_inuse_init() and sock_prot_inuse_free() to abstract pcounter use. 2) if CONFIG_PROC_FS=n, we can zap 'inuse' member from "struct proto", since nobody wants to read the inuse value. This saves 1372 bytes on i386/SMP and some cpu cycles. Signed-off-by: Eric Dumazet Signed-off-by: David S.
