+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.
