    cciss: kernel scan thread for MSA2012 · 0a9279cc
    Mike Miller authored
    The MSA2012 cannot inform the driver of configuration changes since all
    management is out of band.  This is a departure from any storage we have
    supported in the past.  We need some way to detect changes on the topology
    so we implement this kernel thread.  In some instances there's nothing we
    can do from the driver (like LUN failure) so just print out a message.  In
    the case where logical volumes are added or deleted we call
    rebuild_lun_table to refresh the driver's view of the world.
