perf test: Switch to new perf_mmap__read_event() interface for "keep tracking" test
The perf test 'keep tracking' still use the legacy interface. No functional change. Committer testing: # perf test tracking 25: Use a dummy software event to keep tracking : Ok # Signed-off-by: Kan Liang <kan.liang@linux.intel.com> Tested-by: Arnaldo Carvalho de Melo <acme@redhat.com> Cc: Andi Kleen <ak@linux.intel.com> Cc: Jiri Olsa <jolsa@redhat.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Wang Nan <wangnan0@huawei.com> Link: http://lkml.kernel.org/r/1519945751-37786-6-git-send-email-kan.liang@linux.intel.com [ Changed bool parameters from 0 to 'false', as per Jiri comment ] Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
