This change adds uverbs support for allocation/freeing of device memory commands. A new uverbs object is defined of type idr to represent and track the new resource type allocation per context. The API requires provider driver to implement 2 new ib_device callbacks - one for allocation and one for deallocation which return and accept (respectively) the ib_dm object which represents the allocated memory on the device. The support is added via the ioctl command infrastructure only.

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.
