When I try to make f2fs on null_blk device, it always shows "Device
size is not sufficient for F2FS volume",
I am I gave enough space for the file system, i.e, 20GiB. I just want
to know hot to fix it.
this is the output message:

When zone size is large comparing to device size, reserved area size tend to be
large and results in the failure. Can you try with smaller zone size, such as
128MB or 64MB?
