From a5e73c29d9243cc2e889a9d7155f331923eee655 Mon Sep 17 00:00:00 2001 From: Patrick McHardy Date: Mon, 14 Jan 2008 23:45:11 -0800 Subject: [PATCH] [NETFILTER]: nf_conntrack_{tcp,sctp}: shrink state table The TCP and SCTP conntrack state transition tables only holds small numbers, but gcc uses 4 byte per entry for the enum. Switching to an u8 reduces the size from 480 to 120 bytes for TCP and from 576 to 144 bytes for SCTP. Signed-off-by: Patrick McHardy Signed-off-by: David S.
