An expansion field was added to the kernel copy of this structure for future use. See mm/gup_benchmark.c. Add the same expansion field here, so that the IOCTL command decodes correctly. Otherwise, it fails with EINVAL. Signed-off-by: Alison Schofield <alison.schofield@intel.com> Acked-by: Kirill A.

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.
