			As of the Linux 2.6.10 kernel, it is now possible to change the
			IO scheduler for a given block device on the fly (thus making it possible,
			for instance, to set the CFQ scheduler for the system default, but
			set a specific device to use the anticipatory or noop schedulers - which
			can improve that device's throughput).

			To set a specific scheduler, simply do this:

			echo SCHEDNAME > /sys/block/DEV/queue/scheduler

			where SCHEDNAME is the name of a defined IO scheduler, and DEV is the
			device name (hda, hdb, sga, or whatever you happen to have).

			The list of defined schedulers can be found by simply doing
			a "cat /sys/block/DEV/queue/scheduler" - the list of valid names
			will be displayed, with the currently selected scheduler in brackets:

			# cat /sys/block/hda/queue/scheduler
			noop anticipatory deadline [cfq]
			# echo anticipatory > /sys/block/hda/queue/scheduler
			# cat /sys/block/hda/queue/scheduler
			noop [anticipatory] deadline cfq
