Only if CFQ could be modified to add one iops mode, flippable through a
sysfs tunable, things will be much simpler. You will not have to add a
new IO scheduler, no new configuration/stat files in blkcg (which is
already crowded now).

I don't think anybody has shown the code that why CFQ can't be modified
to support iops mode.

Thanks
