Subject: [PATCH V1 03/23] perf evlist: Use libperf functions in evlist__enable_event_idx()
Date: Thu, 5 May 2022 19:56:19 +0300 [thread overview]
Message-ID: <20220505165639.361733-4-adrian.hunter@intel.com> (raw)
In-Reply-To: <20220505165639.361733-1-adrian.hunter@intel.com>
evlist__enable_event_idx() is used only for auxtrace events which are never
system_wide. Simplify by using libperf enable event functions.
