Subject: [PATCH 0/3] perf stat: Fix bperf cgroup counters

Hello,

This fixes a random failures in the perf stat cgroup BPF counters (bperf).
I've also added a new test to ensure it working properly.

You can get it from 'perf/bperf-cgrp-fix-v1' branch in

  git://git.kernel.org/pub/scm/linux/kernel/git/namhyung/linux-perf.git

Thanks,
Namhyung
