-17.7% regression
Greeting,
FYI, we noticed a -17.7% regression of phoronix-test-suite.fio.SequentialRead.IO_uring.Yes.No.1MB.DefaultTestDirectory.mb_s due to commit:
commit: 1a0a67f5efc83d6ca15c1e12471175f6f7db550b ("[PATCH] workqueue: Use active mask for new worker when pool is DISASSOCIATED")
url: https://github.com/intel-lab-lkp/linux/commits/Schspa-Shi/workqueue-Use-active-mask-for-new-worker-when-pool-is-DISASSOCIATED/20220707-170740
base: https://git.kernel.org/cgit/linux/kernel/git/tj/wq.git for-next
patch link: https://lore.kernel.org/lkml/20220707090501.55483-1-schspa@gmail.com
in testcase: phoronix-test-suite
on test machine: 96 threads 2 sockets Intel(R) Xeon(R) Gold 6252 CPU @ 2.10GHz with 512G memory
with following parameters:
test: fio-1.14.1
option_a: Sequential Read
option_b: IO_uring
option_c: Yes
option_d: No
option_e: 1MB
option_f: Default Test Directory
cpufreq_governor: performance
ucode: 0x500320a
test-description: The Phoronix Test Suite is the most comprehensive testing and benchmarking platform available that provides an extensible framework for which new tests can be easily added.

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.
