See 'Maximum On-Disk Sizes of the Filesystems' on
| Kernel 2.6: For both 32-bit systems with option CONFIG_LBD set and for
| 64-bit systems: The size of a file system is limited to 2^73 (far too
| much for today). On 32-bit systems the size of a file is limited to 2
| TiB. Note that not all filesystems and hardware drivers might handle
| such large filesystems.
