Subject: [clocksource]  df29d3cd5a:  stress-ng.clock.ops_per_sec 4.5%
 improvement



Greeting,

FYI, we noticed a 4.5% improvement of stress-ng.clock.ops_per_sec due to commit:


commit: df29d3cd5ad4d400767caa199ec7c0ecbab10fc8 ("clocksource: Limit number of CPUs checked for clock synchronization")
https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git master


in testcase: stress-ng
on test machine: 96 threads 2 sockets Intel(R) Xeon(R) Gold 6252 CPU @ 2.10GHz with 512G memory
with following parameters:

	nr_threads: 100%
	disk: 1HDD
	testtime: 60s
	class: interrupt
	test: clock
	cpufreq_governor: performance
	ucode: 0x5003006






Details are as below:
-------------------------------------------------------------------------------------------------->


To reproduce:

        git clone https://github.com/intel/lkp-tests.git
        cd lkp-tests
        bin/lkp install                job.yaml  # job file is attached in this email
        bin/lkp split-job --compatible job.yaml  # generate the yaml file for lkp run
        bin/lkp run                    generated-yaml-file
