base: https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git 5e857ce6eae7ca21b2055cca4885545e29228fe2

in testcase: unixbench
on test machine: 192 threads Intel(R) Xeon(R) Platinum 9242 CPU @ 2.30GHz with 192G memory
with following parameters:

	runtime: 300s
	nr_task: 30%
	test: syscall
	cpufreq_governor: performance
