Hi,
I see that the reproduction program you pasted is the following:
```
dmsetup remove_all
wipefs -a --force /dev/sda1
mkfs -t ext4 -q -F /dev/sda1
mkdir -p /fs/sda1
mount -t ext4 /dev/sda1 /fs/sda1
for cpu_dir in /sys/devices/system/cpu/cpu[0-9]*
do
online_file="$cpu_dir"/online
[ -f "$online_file" ] && [ "$(cat "$online_file")" -eq 0 ] && continue
file="$cpu_dir"/cpufreq/scaling_governor
[ -f "$file" ] && echo "performance" > "$file"
done
"mkdir" "-p" "/mnt/stress-ng"
"mount" "/dev/sda1" "/mnt/stress-ng"
"stress-ng" "--timeout" "60" "--times" "--verify" "--metrics-brief"
"--ramfs" "9"
```
Looks like it will do mount and umount stress tests.
The commit 475733dda5ae ("mm: vmscan: add shrinker_srcu_generation")
has optimized the umount, can you test it again with this commit?
Thanks,
Qi

> 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.
