Changes since v1: - Check event->attr.sample_type & PERF_SAMPLE_RAW before calling perf_sample_save_raw_data(). - Subject has been changed to reflect the change of solution. Changes since v2: - Move sample_type check into perf_sample_save_raw_data(). - (New patch) Move sample_type check into perf_sample_save_callchain(). - (New patch) Move sample_type check into perf_sample_save_brstack().
