Subject: [PATCH 05/35] tools lib traceevent, perf tools: Rename pevent alloc / free APIs
Date:   Wed, 15 Aug 2018 12:05:41 -0300
Message-Id: <20180815150611.32080-6-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 "pevent_". This changes
APIs: pevent_alloc, pevent_free, pevent_event_info and pevent_func_resolver_t
