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] 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:

Their call stack is as follows:

cat /proc/42330/stack

[<0>] __synchronize_srcu.part.21+0x83/0xb0
[<0>] unregister_shrinker+0x85/0xb0
[<0>] deactivate_locked_super+0x27/0x70

[<0>] task_work_run+0x65/0x90

[<0>] do_syscall_64+0x44/0x80
[<0>] entry_SYSCALL_64_after_hwframe+0x63/0xcd

+ 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
