Subject: [PATCH 16/35] tools lib traceevent,  perf tools: Rename traceevent_plugin_* APIs
Date:   Wed, 15 Aug 2018 12:05:52 -0300
Message-Id: <20180815150611.32080-17-acme@kernel.org>
In-Reply-To: <20180815150611.32080-1-acme@kernel.org>
References: <20180815150611.32080-1-acme@kernel.org>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

From: "Tzvetomir Stoyanov (VMware)" <tz.stoyanov@gmail.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_" and not "traceevent_". This changes
APIs: traceevent_plugin_list_options, traceevent_plugin_free_options_list,
traceevent_plugin_add_options, traceevent_plugin_remove_options,
traceevent_print_plugins
