    [PATCH] device-mapper: Fix queue_if_no_path initialisation · 485ef69e
    Alasdair G Kergon authored
    When creating a multipath device, if the queue_if_no_path parameter is
    specified it gets ignored.
    
    While the queue_if_no_path variable is correctly set to 1, the
    saved_queue_if_no_path gets set to 0.  When the device is subsequently made
    live (resumed), the saved value (0) always overwrites the live value (1) so
    the option *always* gets turned off.
    
    The fix adds a parameter to the queue_if_no_path() function to indicate
    whether the previous value should be preserved or not - if not, as when the
    device is being set up, the saved value is set to the new value (1).
