Hello,

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?
We tested commit 475733dda5ae and the regression persists on it. Please
check the details as below:
Thanks for the testing.
After looking at the test data below more carefully, I found that there
is no perf hotspot of the shrink_slab(). That is, is the memory
reclamation not triggered during the test?
If this is the case, the only difference between 42c9db3970483 and
f95bdb700bc6b is that there is one more call to synchronize_srcu(), and
no one is in the critical section of shrinker_srcu at this time. It is
strange that this can cause such a large performance regression, I will
try to reproduce and continue to investigate the cause.
Well, I just ran the following command and reproduced the result:
stress-ng --timeout 60 --times --verify --metrics-brief --ramfs 9 &
1) with commit 42c9db3970483:

2) with commit f95bdb700bc6b:

stress-ng: info: [37676] stressor bogo ops real time usr time

stress-ng: info: [37676] successful run completed in 60.10s (1 min,
0.10 secs)
The bogo ops/s (real time) did drop significantly.
And the memory reclaimation was not triggered in the whole process. so
theoretically no one is in the read critical section of shrinker_srcu.
Then I found that some stress-ng-ramfs processes were in
TASK_UNINTERRUPTIBLE state for a long time:

+ RCU folks, Is this result as expected? I would have thought that
synchronize_srcu() should return quickly if no one is in the read
critical section. :(

Qi
