|   | What:		/sys/block/<device>/iosched/target_latency | ||
|  | Date:		March 2012 | ||
|  | contact:	Tao Ma <boyu.mt@taobao.com> | ||
|  | Description: | ||
|  | 		The /sys/block/<device>/iosched/target_latency only exists | ||
|  | 		when the user sets cfq to /sys/block/<device>/scheduler. | ||
|  | 		It contains an estimated latency time for the cfq. cfq will | ||
|  | 		use it to calculate the time slice used for every task. |
