looking at /usr/include/ufs/ufs/dinode.h - i see
and i have really no idea why time uses as much as 8+4 bytes like that:
ufs_time_t di_mtime; /* 40: Last modified time. */
int32_t di_mtimensec; /* 64: Last modified time. */
i think it is not a problem to make link count 32-bit, and - why "spare"
space are not just used for more direct/indirect blocks
