		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

		HugePages_Total is the size of the pool of hugepages.
		HugePages_Free is the number of hugepages in the pool that are not yet

		HugePages_Rsvd is short for "reserved," and is the number of hugepages

		allocation has yet been made. It's vaguely analogous to overcommit.
