6.10-stable review patch. If anyone has any objections, please let me know.
------------------
From: Namhyung Kim <namhyung@xxxxxxxxxx>
[ Upstream commit caa463bb79a82ac5fce05a0dcf7893d94c84fc5e ]
The new --per-cluster option was added recently but it forgot to update
the aggr_header fields which are used for --metric-only option. And it
resulted in a segfault due to NULL string in fputs().
Fixes: cbc917a1b03b ("perf stat: Support per-cluster aggregation")
