The ability to use a mounted device node as the primary argument to xfs_growfs was added back in with: 7e8275f8 xfs_growfs: allow mounted device node as argument because it was an undocumented behavior that some userspace depended on. This test exercises that functionality. Signed-off-by: Eric Sandeen <sandeen@redhat.com> Reviewed-by: Zorro Lang <zlang@redhat.com> Signed-off-by: Eryu Guan <guaneryu@gmail.com>
