771 | Enable support for disk partitions within SPL. 'Disk' is something | |
772 | of a misnomer as it includes non-spinning media such as flash (as | |

775 | at the start or end which describes the location and size of each | |
776 | 'partition'. These partitions are typically uses as individual block | |
