..._shutdown was to let us specify different behaviors at the libnbd level, rather than NBD protocol flags (for that, the user has nbd_aio_disconnect). But when we later parameterized OFlags to accept various bitmasks (commit f891340b), we failed to mark nbd_shutdown as using a different bitmask than NBD_CMD_FLAG. I've finally found a use for such a flag. By itself, nbd_aio_disconnect merely queues itself at the back of all pending commands. But if the server is processing responses slowly, it can be desirable to elevate a disconnect request to the front of the queue, intentionally abandoning all sub...
