+       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.
+
+       This option only enables generic Block IO controller infrastructure.
+       One needs to also enable actual IO controlling logic in CFQ for it
+       to take effect. (CONFIG_CFQ_GROUP_IOSCHED=y).
