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.
