Hello Alice,

Some of the code in drivers/scsi/scsicam.c duplicates code in
block/partitions/msdos.c and block/genhd.c. I think patches that remove
the partition table parsing code from drivers/scsi/scsicam.c and that
use the generic partition table parsing code instead would be more than
welcome.

Bart.
