From: Linus Torvalds Date: Wed, 16 Mar 2011 15:04:07 +0000 (-0700) Subject: Increase OSF partition limit from 8 to 18 X-Git-Tag: v2.6.32.40~74 X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=06200342c9c021c4ff13e7d8d1a4a568c324d6a9;p=karo-tx-linux.git 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.
