Could you split many patches for every file changed, and add test suite in execution file?

> +Description
> +-----------
> +
> +This test is a basic multiple pthread test which demonstrates the basics
> of control group. Cgroup is a Linux kernel feature that limits, accounts
> for and isolates the resource usage, like CPU, memory, disk I/O, network,
> etc of a collection of processes. Now, it's focus on the CPU usage.

> +Prerequisites
> +-------------
> +Support igb_uio driver, kernel is 3.11+. Use "modeprobe uio" "modprobe
> igb_uio" and then use "./tools/dpdk_nic_bind.py --bind=igb_uio
> device_bus_id" to bind the ports.
