 The following parameters can be specified to setup the controller:
 
-* **`blkioWeight`** *(uint16, OPTIONAL)* - specifies per-cgroup weight. This is default weight of the group on all devices until and unless overridden by per-device rules. The range is from 10 to 1000.

-* **`blkioLeafWeight`** *(uint16, OPTIONAL)* - equivalents of `blkioWeight` for the purpose of deciding how much weight tasks in the given cgroup has while competing with the cgroup's child cgroups. The range is from 10 to 1000.
+* **`blkioLeafWeight`** *(uint16, OPTIONAL)* - equivalents of `blkioWeight` for the purpose of deciding how much weight tasks in the given cgroup has while competing with the cgroup's child cgroups.
 
 * **`blkioWeightDevice`** *(array of objects, OPTIONAL)* - specifies the list of devices which will be bandwidth rate limited. The following parameters can be specified per-device:
     * **`major, minor`** *(int64, REQUIRED)* - major, minor numbers for device. More info in `man mknod`.
-    * **`weight`** *(uint16, OPTIONAL)* - bandwidth rate for the device, range is from 10 to 1000

     You MUST specify at least one of `weight` or `leafWeight` in a given entry, and MAY specify both.
