| Subject: [PATCH] Increase OSF partition limit from 8 to 18 |
| |
| commit 34d211a2d5df4984a35b18d8ccacbe1d10abb067 upstream. |
| |
| It turns out that while a maximum of 8 partitions may be what people |
| "should" have had, you can actually fit up to 18 entries(*) in a sector. |
| |
| And some people clearly were taking advantage of that, like Michael |
| Cree, who had ten partitions on one of his OSF disks. |
| |
| (*) The OSF partition data starts at byte offset 64 in the first sector, |
| and the array of 16-byte partition entries start at offset 148 in |
| the on-disk partition structure. |
