Revision 0e6e1db4ac7acfe3e38bbef9eba59233ba7f6b9a authored by Bob Copeland on 17 January 2006, 06:14:20 UTC, committed by Linus Torvalds on 17 January 2006, 07:15:29 UTC
The Rio Karma portable MP3 player has its own proprietary partition table. The partition layout is similar to a DOS boot sector but it begins at a different offset and uses a different magic number (0xAB56 instead of 0xAA55). Add support for it to enable mounting the device. Signed-off-by: Bob Copeland <me@bobcopeland.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
