[PATCH 08/34] perf stat: Update or print per-thread stats

From: Arnaldo Carvalho de Melo
Date: Thu Dec 14 2017 - 12:52:18 EST


From: Jin Yao <yao.jin@xxxxxxxxxxxxxxx>

If the stats pointer in stat_config structure is not null, it will
update the per-thread stats or print the per-thread stats on this
buffer.
