drbd: Allow attaching of a newly created device to any backing device
A newly created device was never exposed before, i.e. has a exposed_data_uuid of 0. Then it is valid to attach to any current_uuid of a backing device (of course also to a newly created one (4)) Signed-off-by: Philipp Reisner <philipp.reisner@linbit.com> Signed-off-by: Lars Ellenberg <lars.ellenberg@linbit.com> Signed-off-by: Jens Axboe <axboe@fb.com>
