IIUC, I think we can delete max_write_same_sectors from rsp as well given
the earlier change in setup_request_queue and rnbd_clt_set_dev_attr.
No, I don't think it's a good idea, we need to keep the protocol
compatible, so client for old kernel version
won't be confused.
Fair enough. Then I guess it is better to add obsolete_ prefix like
obsolete_rotational.
