From 6823645d608541c2c69e8a99454936e058c294e0 Mon Sep 17 00:00:00 2001 From: Patrick McHardy Date: Sat, 7 Jul 2007 22:30:49 -0700 Subject: [NETFILTER]: nf_conntrack_expect: function naming unification Currently there is a wild mix of nf_conntrack_expect_, nf_ct_exp_, expect_, exp_, ... Consistently use nf_ct_ as prefix for exported functions. Signed-off-by: Patrick McHardy Signed-off-by: David S.
