So, set size to 38M for f2fs.
It looks f2fs-utils 1.14.0 needs at least 52 MB space for f2fs image.
mkfs.f2fs /dev/zram0 13056 -f

Thanks,
My F2FS-tools is mkfs.f2fs Ver: 1.9.0 (2017-09-21). So, is 52MB enough?
The image size f2fs needed seems growing.
Thanks.

I have tried from 25M, until 38M, it passed.
