Subject: [PATCH v2 0/5] Fixes for setting event freq/periods

Some fixes that address issues for regular and pfm4 events with 2
additional perf_event_attr tests. Various authors, David Sharp isn't
currently at Google.

v2. corrects the commit message following Athira Rajeev's suggestion.

David Sharp (1):
  perf record: Set PERF_RECORD_PERIOD if attr->freq is set.

Ian Rogers (3):
  perf test: Ensure sample_period is set libpfm4 events
  perf record: Don't clear event's period if set by a term
  perf test: Leader sampling shouldn't clear sample period

Stephane Eranian (1):
  perf record: Prevent override of attr->sample_period for libpfm4
    events
