How about pointing out the old issue has been fixed with below patch:

f2fs-tools: fix to check total valid block count before block allocation

Otherwise, user should keep kernel commit "f2fs: don't clear
CP_QUOTA_NEED_FSCK_FLAG".

Thanks,

p.alloc_mode == LFS will be more straightforward. :)

Anyway,

Actually, that didn't fix my testing issue, but I found we were not using
error control for quota_sysfile. Now I've seen no issue with the below patch.

Subject: [PATCH] f2fs: link f2fs quota ops for sysfile

This patch reverts:
commit fb40d618b039 ("f2fs: don't clear CP_QUOTA_NEED_FSCK_FLAG").

We were missing error handlers used in f2fs quota ops.
