Message-Id: <1343835928-21541-1-git-send-email-vapier@gentoo.org>
Date: Wed, 1 Aug 2012 11:45:23 -0400
From: Mike Frysinger <vapier@...too.org>
To: YOSHIFUJI Hideaki <yoshfuji@...ux-ipv6.org>
Cc: netdev@...r.kernel.org
Subject: [PATCH 1/6] tracepath: re-use printf return in print_host
Since the printf funcs already return the length of chars displayed,
use that value instead of re-calculating the length with strlen.
