I was just preparing my environment so I could hit the same issue
before I go for the bisect, so I don't need to reboot every time. Got
to a point where I could just qemu kvm + initrd ramdisk with / (f2fs)
and I could hit the problem almost every 8/10 runs just by doing
"mount -o remount /" and the system would freeze. That's good. I've a
good test case! ... and then I see Chao Yu's patch ...

Ok, the patch seems to fix the problem. I'll run my qemu kvm
environment a few more times before I switch the real system. Because
it's not a that I could cause a real "mount -o remount /" freeze or
"vi /etc/passwd" fault all the time,

Will feedback soon. This would a very nice year end celebration so I
could move to 6.2.0-rc1.

Thank you!
