If you look at the block size extension, the size of the disk must be an exact
multiple of the minimum block size. So that would work.
But there is no guarantee that disk_size/block_size < INT_MAX.. May be,
additional option, specifying the shift would be better. With convention
that if offset+length exceeds disk size, length should be recalculated
as disk_size-offset.
