| |
The perf_stat_config.aggr_map should have a correct size of the aggregation map. Use it to allocate aggr_counts.
Also AGGR_NONE with per-core events can be tricky because it doesn't aggreate basically but it needs to do so for per-core events only. So only per-core evsels will have stats->aggr data.
Note that other caller of evlist__alloc_stat() might not have stat_config or aggr_map.
