Subject: [PATCH v3 0/3] perf:core: Save raw sample data

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().

Original commit message from v1:
perf/core: Trim dyn_size if raw data is absent

Yabin Cui (3):
  perf/core: Save raw sample data conditionally based on sample type
  perf: core: Check sample_type in perf_sample_save_callchain
  perf: core: Check sample_type in perf_sample_save_brstack
