Subject: [mm/munlock] 237b445401: stress-ng.remap.ops_per_sec -62.6%
regression
Greeting,
FYI, we noticed a -62.6% regression of stress-ng.remap.ops_per_sec due to commit:
commit: 237b4454014d3759acc6459eb329c5e3d55113ed ("[PATCH v2 07/13] mm/munlock: mlock_pte_range() when mlocking or munlocking")
url: https://github.com/0day-ci/linux/commits/Hugh-Dickins/mm-munlock-rework-of-mlock-munlock-page-handling/20220215-104421
base: https://git.kernel.org/cgit/linux/kernel/git/tip/tip.git ee28855a54493ce83bc2a3fbe30210be61b57bc7
patch link: https://lore.kernel.org/lkml/d39f6e4d-aa4f-731a-68ee-e77cdbf1d7bb@google.com
in testcase: stress-ng
on test machine: 128 threads 2 sockets Intel(R) Xeon(R) Platinum 8358 CPU @ 2.60GHz with 128G memory
with following parameters:
nr_threads: 100%
testtime: 60s
class: memory
test: remap
cpufreq_governor: performance
ucode: 0xd000280
If you fix the issue, kindly add following tag
Reported-by: kernel test robot <oliver.sang@...el.com>
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.
