Hi pals, I'm now looking into zfs source and have been
puzzled about 128-bit. It's announced that ZFS is an 128-bit file
system. But what does 128-bit mean? Does that mean the addressing
capability is 2^128? But in the source, 'zp_size' (in 'struct
znode_phys'), the file size in bytes, is defined as uint64_t. So I
guess 128-bit may be the bit width of the zpool pointer, but where is
it defined?
Regards,
Wu Shu
