Message-Id: <1441913708-15532-7-git-send-email-matthias.tafelmeier@gmx.net>
Date: Thu, 10 Sep 2015 21:35:04 +0200
From: Matthias Tafelmeier <matthias.tafelmeier@....net>
To: netdev@...r.kernel.org
Cc: hagen@...u.net, shemminger@...l.org, fw@...len.de,
edumazet@...gle.com, daniel@...earbox.net
Subject: [PATCH v7 06/10] ss: renaming and export of current_filter
Exported current_filter as ss_current_filter, because in
the fmt handlers, I need that piece of info to resolve out issues of json.
