[PATCH v1 04/10] perf stat: Modify the group test

From: Ian Rogers
Date: Wed Mar 01 2023 - 23:13:47 EST


Previously nr_members would be 0 for an event with no group. The
previous change made that count 1, the event is its own leader without
a group. Make the find_stat logic consistent with this, an improvement
suggested by Namhyung Kim.
