0004 Description:
0005                 The /sys/block/<device>/iosched/target_latency only exists
0006                 when the user sets cfq to /sys/block/<device>/scheduler.
0007                 It contains an estimated latency time for the cfq. cfq will
0008                 use it to calculate the time slice used for every task.
