| 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.
