From 156776a3e29491b363fdc9811912e1298655d060 Mon Sep 17 00:00:00 2001

Subject: [PATCH] ustat02: Fix EFAULT in 32bit compatibility mode
The size of dev_t is larger than 32 bits which causes the dev argument
to be passed incorrectly. On Arm this means that the EFAULT test case
actually returns EINVAL because the device number isn't recognised.
