    [SCSI] hpsa: remove scan thread · 31468401

    The intent of the scan thread was to allow a UNIT ATTENTION/LUN
    DATA CHANGED condition encountered in the interrupt handler
    to trigger a rescan of devices, which can't be done in interrupt
    context.  However, we weren't able to get this to work, due to
    multiple such UNIT ATTENTION conditions arriving during the rescan,
    during updating of the SCSI mid layer, etc.  There's no way to tell
    the devices, "stand still while I scan you!"  Since it doesn't work,
    there's no point in having the thread, as the rescan triggered via
    ioctl or sysfs can be done without such a thread.
