Subject: [PATCH 2/6] tools/lib/traceevent: Rename struct cmdline to struct tep_cmdline
Date: Fri, 30 Nov 2018 23:08:09 -0500
Message-ID: <20181201040852.358871851@goodmis.org> (raw)
In-Reply-To: <20181201040807.154099010@goodmis.org>

From: Tzvetomir Stoyanov <tstoyanov@vmware.com>

In order to make libtraceevent into a proper library, variables, data
structures and functions require a unique prefix to prevent name space
conflicts. That prefix will be "tep_".
This patch renames struct cmdline to struct tep_cmdline.
