dm array: if resizing the array is a noop set the new root to the old one This could've been quite bad (to return success but not update the new root to point at the old) but in practice the only known consumer of the dm array code is the DM cache target. And the DM cache target passes in the same old root to array_resize() anyway. Signed-off-by: Joe Thornber <ejt@redhat.com> Signed-off-by: Mike Snitzer <snitzer@redhat.com>
