Subject: [PATCH] selftests/vm/gup_benchmark.c: match gup struct to kernel
Date: Fri, 7 Dec 2018 18:06:45 -0800	[thread overview]
Message-ID: <20181208020645.GA28467@alison-desk.jf.intel.com> (raw)

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.
