Subject: [block] cb2ac2912a:
fxmark.ssd_f2fs_dbench_client_4_bufferedio.works/sec -66.0% regression
Greeting,
FYI, we noticed a -66.0% regression of fxmark.ssd_f2fs_dbench_client_4_bufferedio.works/sec due to commit:
commit: cb2ac2912a9ca7d3d26291c511939a41361d2d83 ("block: reduce kblockd_mod_delayed_work_on() CPU consumption")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
in testcase: fxmark
on test machine: 24 threads 1 sockets Intel Atom(R) P5362 processor with 64G memory
with following parameters:
disk: 1SSD
media: ssd
test: dbench_client
fstype: f2fs
directio: bufferedio
cpufreq_governor: performance
ucode: 0x9c02000e
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.
