... if a map has been flushed. In this case, we know that the
the paths haven't been multipathed by coalesce_paths() because of the current
configuration (failure to create the map can't be the reason if the map
exists in coalesce_maps()). Make sure udev sees the paths which have
been released from the map as non-multipath.
Note that this is the only case where maps are flushed where it is correct
to trigger paths uevents. In other cases, e.g. after a "remove map" CLI
command, the configuration is unchanged and if we triggered an uevent,
the map would be re-created by multipathd when the uevent arrived.
