Hi Tejun,

Can you please also update blkio-controller.txt file to reflect the
fact that now throttling also supports hierarchy. One of the places
which needs updation is following.

Hierarchical Cgroups
====================
- Currently only CFQ supports hierarchical groups. For throttling,
cgroup interface does allow creation of hierarchical cgroups and
internally it treats them as flat hierarchy.

Thanks
Vivek
