Subject: [sched/fair]  8b4e74ccb5:  stress-ng.sem.ops_per_sec 12.0%
 improvement



Greeting,

FYI, we noticed a 12.0% improvement of stress-ng.sem.ops_per_sec due to commit:


commit: 8b4e74ccb582797f6f0b0a50372ebd9fd2372a27 ("sched/fair: Fix detection of per-CPU kthreads waking a task")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.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%
	testtime: 60s
	sc_pid_max: 4194304
	class: scheduler
	test: sem
	cpufreq_governor: performance
	ucode: 0x5003102






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


To reproduce:

        git clone https://github.com/intel/lkp-tests.git
        cd lkp-tests
        sudo 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
        sudo bin/lkp run generated-yaml-file

        # if come across any failure that blocks the test,
        # please remove ~/.lkp and /lkp dir to run from a clean state.
