Oops, I mean:
#regzbot introduced v6.1.1..72a85e2b0a1e1e
Also, Cc'ed other F2FS maintainers and relevant lists.
Thanks.

Well, that indeed is unfortunate and ideally shouldn't happen, but the
simple reality is: that can happen this time of the year due to this
thing called "festive season".

The usual: bisect the issue, as then (a) we know exactly which developer
caused it, (b) which subsystem/maintainer is responsible (issues in a fs
might be caused by the VFS, block layer, mm, ...), and (c) might be able
to quickly revert that culprit, even if the people normally responsible
are MIA for some reason.
Ciao, Thorsten (wearing his 'the Linux kernel's regression tracker' hat)
P.S.: As the Linux kernel's regression tracker I deal with a lot of
reports and sometimes miss something important when writing mails like
this. If that's the case here, don't hesitate to tell me in a public
reply, it's in everyone's interest to set the public record straight.

FWIW, I've tested f2fs on mainline in the last few days, and I haven't seen
this. The following works fine, for example:
mkfs.f2fs -f /dev/vdb
mount /dev/vdb /mnt
vim
# write something, then ':w /mnt/file'
If you could provide the mkfs and mount options you are using, and any other
relevant details, that would be helpful. Bisection would also be very helpful,
as Thorsten mentioned.

It's been a long time since I saw Kim and Chao respond to messages. I think
it may be because of the holiday in the US，and China loosened restrictions
on COVID-19 (lots of people got sick, I just recovered today).
BTW, the log you uploaded corresponds to which kernel git is, and which
commit it corresponds to.
Thx,

Other than that, I found some cases which can cause similar issue, so I figure
out a patch for possible fixing, if you can have a try with it to check whether
it can fix your issue, that would be helpful as well.

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!

Ok, no more freeze, no more errors! All good. I'm finally on the
latest linux-6.2.0-rc1 with the patch.
Happy new year!
My best,
Jeff
[TLDR: This mail in primarily relevant for Linux regression tracking. A
change or fix related to the regression discussed in this thread was
posted or applied, but it did not use a Link: tag to point to the
report, as Linus and the documentation call for. Things happen, no
worries -- but now the regression tracking bot needs to be told manually
about the fix. See link in footer if these mails annoy you.]
