Subject: selftests/vm/gup_benchmark.c: match gup struct to kernel
X-Git-Tag: microblaze-v5.4-rc1~1432^2~8
X-Git-Url: http://git.monstr.eu/?a=commitdiff_plain;h=91cd63d320f84dcbf21d4327f31f7e1f85adebd0;p=linux-2.6-microblaze.git

selftests/vm/gup_benchmark.c: match gup struct to kernel

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.
