Subject[PATCH 01/11] perf stat: Fix crash with --per-node --metric-only in CSV mode
Date
The following command will get segfault due to missing aggr_header_csv
for AGGR_NODE:

$ sudo perf stat -a --per-node -x, --metric-only true

Fixes: 86895b480a2f ("perf stat: Add --per-node agregation support")
