6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Tengda Wu <wutengda@huaweicloud.com>
[ Upstream commit d36e5b36a2928b30e09ff59ce5ce2d5df935176e ]
Replace `brstack` workload with `sqrtloop` workload, because `sqrtloop`
workload contains fork(), which is suitable for testing the bperf event
inheritance feature.
