Replace every explicit mount/umount of scratch or test devices with helper functions. This allows the next patch to add in hooks to these functions in order to set up & tear down overlayfs on every mount/umount (also adds _test_unmount(), which didn't exist prior) [Eryu Guan rebased the patch agains latest master and replaced more mount/umount with helpers] Signed-off-by: Eryu Guan <eguan@redhat.com> Signed-off-by: Eric Sandeen <esandeen@redhat.com> Reviewed-by: Dave Chinner <dchinner@redhat.com> Signed-off-by: Dave Chinner <david@fromorbit.com>
