Description: IO controller

More info: Generic block IO controller cgroup interface. This is the common cgroup interface which should be used by various IO controlling policies. Currently, CFQ IO scheduler uses it to recognize task groups and control disk bandwidth allocation (proportional time slice allocation) to such task groups. It is also used by bio throttling logic in block layer to implement upper limit in IO rates on a device. This option only enables generic Block IO controller infrastructure. One needs to also enable actual IO controlling logic/policy. For enabling proportional weight division of disk bandwidth in CFQ, set CONFIG_BFQ_GROUP_IOSCHED=y; for enabling throttling policy, set CONFIG_BLK_DEV_THROTTLING=y. See Documentation/admin-guide/cgroup-v1/blkio-controller.rst for more information.
