From 84a3aa000eacbaf841d745b07ef3a3280899056b Mon Sep 17 00:00:00 2001 From: Pavel Emelyanov Date: Wed, 16 Jul 2008 20:19:08 -0700 Subject: ipv4: prepare net initialization for IP accounting Some places, that deal with IP statistics already have where to get a struct net from, but use it directly, without declaring a separate variable on the stack. So, save this net on the stack for future IP_XXX_STATS macros. Signed-off-by: Pavel Emelyanov Signed-off-by: David S.
