If the "--dry-run" of fsck.f2fs is similar with "-n -y" of fsck.ext4. Then
you might need to change the fsck_opts() function in common/config.
_fsck_opts()
{
case $FSTYP in
ext2|ext3|ext4)
export FSCK_OPTIONS="-nf"
;;
reiser*)
export FSCK_OPTIONS="--yes"
;;
f2fs)
export FSCK_OPTIONS=""
;;
...
}
The default FSCK_OPTIONS for f2fs should be "--dry-run".
f2fs)
export FSCK_OPTIONS="--dry-run"
Then ...

... then you can save this export FSCK_OPTIONS="--dry-run". I've explained
more in your v1 patch review, refer to:
