This is modeled after the similar EFA enablement in commit
66f4817b57 ("RDMA/efa: Add support for dmabuf memory regions").
Like EFA there is no support for revocation so we simply call the
ib_umem_dmabuf_get_pinned() to obtain a umem instead of the normal
ib_umem_get(). Everything else stays the same.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
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.
