Gang Li 448ce0e6ea perf stat: Enable ignore_missing_thread ... perf already support ignore_missing_thread for -p, but not yet applied to `perf stat -p <pid>`. This patch enables ignore_missing_thread for `perf stat -p <pid>`. Committer notes: And here is a refresher about the 'ignore_missing_thread' knob, from a previous patch using it: ca8000684e ("perf evsel: Enable ignore_missing_thread for pid option") --- While monitoring a multithread process with pid option, perf sometimes may return sys_perf_event_open failure with 3(No such process) if any of the process's threads die before we open the event. However, we want perf continue monitoring the remaining threads and do not exit with error. --- Signed-off-by: Gang Li <ligang.bdlg@bytedance.com> Cc: Alexander Shishkin <alexander.shishkin@linux.intel.com> Cc: Ingo Molnar <mingo@redhat.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Mark Rutland <mark.rutland@arm.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Peter Zijlstra <peterz@infradead.org> Link: https://lore.kernel.org/r/20220622030037.15005-1-ligang.bdlg@bytedance.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>		2022-06-26 12:32:55 -03:00
