Cgroups can be guaranteed a minimum number of "cpu shares"
when a system is busy.
This does not limit a cgroup's CPU usage if the CPUs are not busy.

This provides accounting for CPU usage by groups of tasks.
.TP
.I cpuset
This cgroup can be used to bind the tasks in a cgroup to
a specified set of CPUs and NUMA nodes.

.I blkio
The
.I blkio
cgroup controls and limits access to specified block devices by
applying IO control in the form of throttling and upper limits against leaf
nodes and intermediate nodes in the storage hierarchy.
Two policies are available.
The first is a proportional-weight time-based division
of disk implemented with CFQ.
This is in effect for leaf nodes using CFQ.
The second is a throttling policy which specifies
upper I/O rate limits on a device.
