Subject[072/143] Increase OSF partition limit from 8 to 18
2.6.32-longterm review patch.  If anyone has any objections, please let us know.

From: Linus Torvalds <>

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.
