 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.
