Subject: [PATCH 12/14] perf test: Apply new perf_mmap__read_event() interface for switch-tracking
Date: Thu, 1 Mar 2018 18:09:09 -0500 [thread overview]
Message-ID: <1519945751-37786-12-git-send-email-kan.liang@linux.intel.com> (raw)
In-Reply-To: <1519945751-37786-1-git-send-email-kan.liang@linux.intel.com>
From: Kan Liang <kan.liang@linux.intel.com>
The perf test 'switch-tracking' still use the legacy interface.
No functional change.
