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.
