Subject: [mm/munlock]  b67bf49ce7:  stress-ng.mlock.ops_per_sec 61.6%
 improvement



Greeting,

FYI, we noticed a 61.6% improvement of stress-ng.mlock.ops_per_sec due to commit:


commit: b67bf49ce7aae72f63739abee6ac25f64bf20081 ("mm/munlock: delete FOLL_MLOCK and FOLL_POPULATE")
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: 10%
	disk: 1HDD
	testtime: 60s
	fs: ext4
	class: os
	test: mlock
	cpufreq_governor: performance
	ucode: 0x500320a






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.
