    [SCSI] zfcp: fix device registration issues · ad58f7db
    Andreas Herrmann 提交于
    The patch fixes following issues:
    
    (1) Replace scsi_add_device with scsi_scan_target.
    (Thus the rport instead of the scsi_host becomes parent of a
    scsi_target again.)
    
    (2) Avoid scsi_device allocation during registration of an remote port.
    (Would be done during fc_scsi_scan_rport.)
    
    (3) Fix queuecommand behaviour when an zfcp unit is blocked.
    (Call scsi_done with DID_NO_CONNECT instead of returning
    SCSI_MLQUEUE_DEVICE_BUSY otherwise we might end up waiting
    for completion in blk_execute_rq for ever.)
