From 861934c7c888973da8bf621b3959e408531539e1 Mon Sep 17 00:00:00 2001 From: Patrick McHardy Date: Wed, 5 Dec 2007 01:30:29 -0800 Subject: [PATCH] [NETFILTER]: nfnetlink_queue: eliminate impossible switch case We don't need a default case in nfqnl_build_packet_message(), the copy_mode is validated when it is set. Tell the compiler about the possible types and remove the default case. Saves 80b of text on x86_64. Signed-off-by: Patrick McHardy Signed-off-by: David S.
