Added rdma cgroup controller that does accounting, limit enforcement on rdma/IB resources. Added rdma cgroup header file which defines its APIs to perform charging/uncharging functionality. It also defined APIs for RDMA/IB stack for device registration. Devices which are registered will participate in controller functions of accounting and limit enforcements. It define rdmacg_device structure to bind IB stack and RDMA cgroup controller. RDMA resources are tracked using resource pool. Resource pool is per device, per cgroup entity which allows setting up accounting limits on per device basis. Currently resources are defined by the RDMA cgroup. Resource pool is created/destroyed dynamically whenever charging/uncharging occurs respectively and whenever user configuration is done. Its a tradeoff of memory vs little more code space that creates resource pool object whenever necessary, instead of creating them during cgroup creation and device registration time.

README
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
