NBD_OPT_EXPORT_NAME is lousy: per the NBD protocol, any failure requires us to close the connection rather than report an error. Therefore, upstream NBD recently added NBD_OPT_GO as the improved version of the option that does what we want [1], along with NBD_OPT_INFO that returns the same information but does not transition to transmission phase. [1] https://github.com/NetworkBlockDevice/nbd/blob/extension-info/doc/proto.md This is a first cut at the information types, and only passes the same information already available through NBD_OPT_LIST and NBD_OPT_EXPORT_NAME; items like NBD_INFO_BLOCK_SIZE (and thus any use of NBD_REP_ERR_BLOCK_SIZE_REQD) are intentionally left for later patches.
