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 
[PATCH] partitions: Read Rio Karma partition table
 
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.
