Hi, Steve, Ajay,
After this patch and run this testcase, I got an use-after-free report
by KASAN. Short log see [1], full logs see attach "panic.log".
And by simple bisect, I found it may be introduced by:

Hi Zheng,
Can you test:

and see if it fixes the KASAN issue for you?
Hi, Steve, your new patch seems not fixes the KASAN issue.
I run the instance-event.tc with your patch again and get same KASAN
report.
My config is in:

Thanks!
