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.
Not sure it may change again, but at least we need to configure mininum
size of f2fs image to 52MB in xfstest.
Thanks,
Thanks.

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