Test result: # ./perf test list 2>&1 | grep 'Setup struct perf_event_attr' 17: Setup struct perf_event_attr # ./perf test 17 -v 17: Setup struct perf_event_attr : --- start --- test child forked, pid 720198 <SNIP> running './tests/attr/test-record-dummy-C0' <SNIP> test child finished with 0 ---- end ---- Setup struct perf_event_attr: Ok Signed-off-by: Yang Jihong <yangjihong1@huawei.com> Tested-by: Ravi Bangoria <ravi.bangoria@amd.com> Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: Alexander Shishkin <alexander.shishkin@linux.intel.com> Cc: Andi Kleen <ak@linux.intel.com> Cc: Anshuman Khandual <anshuman.khandual@arm.com> Cc: Ian Rogers <irogers@google.com> Cc: Ingo Molnar <mingo@redhat.com> Cc: James Clark <james.clark@arm.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Kan Liang <kan.liang@linux.intel.com> Cc: Mark Rutland <mark.rutland@arm.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Thomas Richter <tmricht@linux.ibm.com> Link: https://lore.kernel.org/r/20230904023340.12707-7-yangjihong1@huawei.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
