-         Conventionally, block device numbers are allocated from
-         predetermined contiguous area.  However, extended block area
-         may introduce non-contiguous block device numbers.  This
-         option forces most block device numbers to be allocated from
-         the extended space and spreads them to discover kernel or
-         userland code paths which assume predetermined contiguous
-         device number allocation.
-
-         Note that turning on this debug option shuffles all the
-         device numbers for all IDE and SCSI devices including libata
-         ones, so root partition specified using device number
-         directly (via rdev or root=MAJ:MIN) won't work anymore.
-         Textual device names (root=/dev/sdXn) will continue to work.
-
-         Say N if you are unsure.
