[PATCH] selftests/vm/gup_benchmark.c: match gup struct to kernel
From: Alison Schofield
Date: Fri Dec 07 2018 - 21:04:27 EST
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.
