From b560580a13b180bc1e3cad7ffbc93388cc39be5d Mon Sep 17 00:00:00 2001 From: Patrick McHardy Date: Sat, 7 Jul 2007 22:35:56 -0700 Subject: [NETFILTER]: nf_conntrack_expect: maintain per conntrack expectation list This patch brings back the per-conntrack expectation list that was removed around 2.6.10 to avoid walking all expectations on expectation eviction and conntrack destruction. As these were the last users of the global expectation list, this patch also kills that. Signed-off-by: Patrick McHardy Signed-off-by: David S.
