+	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).
