From 5962fc6d5fff09c8e6fb8cadcb18327a0f4277f7 Mon Sep 17 00:00:00 2001 From: Patrick McHardy Date: Wed, 18 Feb 2009 15:30:34 +0100 Subject: [PATCH] netfilter: nf_conntrack: don't try to deliver events for untracked connections The untracked conntrack actually does usually have events marked for delivery as its not special-cased in that part of the code. Skip the actual delivery since it impacts performance noticeably.
