Subject: [PATCH 2/2] trace-cmd: Rename tracecmd_get_pevent() to tracecmd_get_tep()
Date: Tue, 22 Dec 2020 14:09:51 +0200	[thread overview]
Message-ID: <20201222120951.492370-3-tz.stoyanov@gmail.com> (raw)
In-Reply-To: <20201222120951.492370-1-tz.stoyanov@gmail.com>

The name of the trace event context from libtraceevent library
is tep, all APIs that work with a pointer to this context should refer
to it as "tep".
