    [SCSI] mpt2sas: fix Integrated Raid unsynced on shutdown problem · 3a9c913a

    Issue:
    IR shutdown(sending) and IR shutdown(complete) messages not
    listed in /var/log/messages when driver is removed.
    
    The driver needs to issue a MPI2_RAID_ACTION_SYSTEM_SHUTDOWN_INITIATED
    request when the driver is unloaded so the IR metadata journal is updated.
    If this request is not sent, then the volume would need a "check
    consistency" issued on the next bootup if the volume was roamed from one
    initiator to another. The current driver supports this feature only when the
    system is rebooted, however this also need to be supported if the driver is
    unloaded
    
    Fix:
    To fix this issue, the driver is going
    to need to call the _scsih_ir_shutdown prior to reporting
    the volumes missing from the OS, hence the device handles
    are still present.
