Jaegeuk,

I'm still struggling troubleshooting this issue.

However, I failed again to reproduce this bug, I doubt the reason may be
my test script and environment(device type/size) is different from yours.
(btw, I used pmem as back-end device, and test w/ all fault injection
points and w/o write_io/checkpoint fault injection points)

Could you please share me your run.sh script? and test command?

And I'd like to ask what's your device type and size?

Thanks,
