Subject: [PATCH 10/10] n_tracerouter and n_tracesink compile configurations.
Date: Thu, 24 Feb 2011 10:07:04 -0800 [thread overview]
Message-ID: <1298570824-26085-11-git-send-email-james_p_freyensee@linux.intel.com> (raw)
In-Reply-To: <james_p_freyensee@linux.intel.com>
From: J Freyensee <james_p_freyensee@linux.intel.com>
This patch allows n_tracerouter and n_tracesink to be compiled and
configured in the Linux kernel.
