From 314ddca3b172fdb9c23a25c545505dbde557602e Mon Sep 17 00:00:00 2001 From: Florian Westphal Date: Wed, 27 Jan 2010 14:38:32 +0100 Subject: [PATCH] netfilter: ebt_limit: add CONFIG_COMPAT support ebt_limit structure is larger on 64 bit systems due to "long" type used in the (kernel-only) data section. Setting .compatsize is enough in this case, these values have no meaning in userspace.
