Enable support for latency based cgroup IO protection
modulename: blk-iolatency.ko
configname: CONFIG_BLK_CGROUP_IOLATENCY
Linux Kernel Configuration
└─>Enable the block layer
└─>Enable support for latency based cgroup IO protection
In linux kernel since version 4.2 (release Date: 2015-08-30)
Enabling this option enables the .latency interface for IO throttling.
The IO controller will attempt to maintain average IO latencies below
the configured latency target, throttling anybody with a higher latency
target than the victimized group.
Note, this is an experimental interface and could be changed someday.
