Subject: [smb3] 5efdd9122e: filebench.sum_operations/s -50.0% regression
Greeting,
FYI, we noticed a -50.0% regression of filebench.sum_operations/s due to commit:
commit: 5efdd9122eff772eae2feae9f0fc0ec02d4846a3 ("smb3: allow deferred close timeout to be configurable")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
in testcase: filebench
on test machine: 88 threads 2 sockets Intel(R) Xeon(R) Gold 6238M CPU @ 2.10GHz (Cascade Lake) with 128G memory
with following parameters:
disk: 1HDD
fs: ext4
fs2: cifs
test: filemicro_delete.f
cpufreq_governor: performance
ucode: 0x5003302

Reported-by: kernel test robot <yujie.liu@...el.com>
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.
