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 Vivek
