		This is a host adapter simulator that can simulate multiple hosts
		each with multiple dummy SCSI devices (disks). It defaults to one
		host adapter with one dummy SCSI disk. Each dummy disk uses kernel
		RAM as storage (i.e. it is a ramdisk). To save space when multiple
		dummy disks are simulated, they share the same kernel RAM for
		their storage. See <http://sg.danny.cz/sg/sdebug26.html> for more
		information. This driver is primarily of use to those testing the
		SCSI and block subsystems. If unsure, say N.
		This pseudo driver simulates one or more hosts (SCSI initiators),
		each with one or more targets, each with one or more logical units.
		Defaults to one of each, creating a small RAM disk device. Many
		parameters found in the /sys/bus/pseudo/drivers/scsi_debug
		directory can be tweaked at run time.
		See <http://sg.danny.cz/sg/sdebug26.html> for more information.
		Mainly used for testing and best as a module. If unsure, say N.
