When a port link is established, the AFU sends a 'link up' interrupt. After the link is up, corresponding initialization steps are performed on the card. Following that, when the card is ready for I/O, the AFU sends 'login succeeded' interrupt. Today, cxlflash invokes scsi_scan_host() upon receipt of both interrupts. SCSI commands sent to the port prior to the 'login succeeded' interrupt will fail with 'port not available' error. This is not desirable. Moreover, when async_scan is active for the host, subsequent scan calls are terminated with error. Due to this, the scsi_scan_host() call performed after 'login succeeded' interrupt could portentially return error and the devices may not be scanned properly. To avoid this problem, scsi_scan_host() should be called only after the 'login succeeded' interrupt. Signed-off-by:

The workqueues "ioc->reset_work_q" and "ioc->fw_event_q" queue a single work item &ioc->fault_reset_work and &fw_event->work, respectively and hence don't require ordering. Hence, they have been converted to use alloc_workqueue(). The WQ_MEM_RECLAIM flag has been set to ensure forward progress under memory pressure since the workqueue belongs to a storage driver which is being used on a memory reclaim path. Since there are fixed number of work items, explicit concurrency limit is unnecessary here. Signed-off-by:

The workqueue "fc_rescan_work_q" queues multiple work items viz &ioc->fc_rescan_work, &ioc->fc_lsc_work, &ioc->fc_setup_reset_work, which require strict execution ordering. Hence, an ordered dedicated workqueue has been used.
