Too short a changeset comment, please elaborate.

The change at least would have to be changed from

"Events: %llu", total_period

to 

"Total period: %llu", total_period

To be consistent in what we call "Events", i.e. right now it is telling
the number of PERF_RECORD_SAMPLE events, with your change it would be
showing the sum of the periods in all samples.
