That said, I'm planning to rebase atop your WIP tree in the short-term for the common nvme opcode + command set decoding bits, that both vhost-nvme and nvme-fabrics code are going to require. --nab -- To unsubscribe from this list: send the line "unsubscribe linux-block" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
