Subject: [xfs] 6191cf3ad5: stress-ng.rename.ops_per_sec -73.5% regression
Greeting,
FYI, we noticed a -73.5% regression of stress-ng.rename.ops_per_sec due to commit:
commit: 6191cf3ad59fda5901160633fef8e41b064a5246 ("xfs: flush inodegc workqueue tasks before cancel")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
in testcase: stress-ng
on test machine: 96 threads 2 sockets Ice Lake with 256G memory
with following parameters:
nr_threads: 10%
disk: 1HDD
testtime: 60s
fs: xfs
class: filesystem
test: rename
cpufreq_governor: performance
ucode: 0xb000280
In addition to that, the commit also has significant impact on the following tests:
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.
