I wrote the below code

    def _common_inner_inner1(inst, *args, **kwargs):
        @mock.patch('cinder.backup.drivers.ceph.rbd')
        @mock.patch('cinder.backup.drivers.ceph.rados')
        def _common_inner_inner2(mock_rados, mock_rbd):
            inst.mock_rados = mock_rados
            inst.mock_rbd = mock_rbd
            inst.mock_rados.ObjectNotFound = MockObjectNotFoundException
            return f(inst, *args, **kwargs)
        return _common_inner_inner2()
    return _common_inner_inner1
