From fb46990dba94866462e90623e183d02ec591cf8f Mon Sep 17 00:00:00 2001 From: Patrick McHardy Date: Wed, 5 Dec 2007 01:23:41 -0800 Subject: [NETFILTER]: nf_queue: remove unnecessary hook existance check We hold a module reference for each queued packet, so the hook that queued the packet can't disappear. Also remove an obsolete comment stating the opposite. Signed-off-by: Patrick McHardy Signed-off-by: David S.
