Shuhei Matsumoto cdf61c2f22 nvme: Polls only the qpair if ctrlr is not fabrics when connecting synchronously ... For non-fabric controllers, the corresponding I/O qpairs are simply re-enabled at controller reset. This had a issue when I/O qpairs span multiple threads and poll group is used. spdk_nvme_ctrlr_reconnect_poll_async() calls nvme_transport_ctrlr_connect_qpair() with qpair->async being false. Then nvme_transport_ctrlr_connect_qpair() calls spdk_nvme_poll_group_process_completions() until the qpair is connected. spdk_nvme_poll_group_process_completions() may poll other qpairs. This may cause I/O to complete on a wrong thread. For PCIe controller, spdk_nvme_poll_group_process_completions() calls spdk_nvme_qpair_process_completions() simply for each qpair. Hence change nvme_transport_ctrlr_connect_qpair() to call spdk_nvme_qpair_process_completions() if the controller is non-fabrics.
