This patch doesn't apply in current tip/perf/core as this logic was moved to perf_evsel/perf_evlist, so that it can be used by other tools.
Please add the 'period' variable to struct perf_record_opts and the sample_type or'ing to perf_evsel__config().
I suggest you use https://github.com/acmel/linux/commits/perf/core for that.
