Navid Emamdoost 20170bfa3d mm/gup: fix memory leak in __gup_benchmark_ioctl
commit a7c46c0c0e3d62f2764cd08b90934cd2aaaf8545 upstream.

In the implementation of __gup_benchmark_ioctl() the allocated pages
should be released before returning in case of an invalid cmd.  Release
pages via kvfree().

README

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.
