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.
