From 772476df7047db87ac4174d1ed396512912d23bf Mon Sep 17 00:00:00 2001 From: Rob Jones Date: Fri, 19 Sep 2014 11:27:51 +0100 Subject: [PATCH] net/netfilter/x_tables.c: use __seq_open_private() Reduce boilerplate code by using __seq_open_private() instead of seq_open() in xt_match_open() and xt_target_open().
