This calculation is based on either a) weight_by_size or b) number of brick who will be assigned the non-zero range So if in case we are not assigning the layout based on weight_by_size, we should choose the "bricks_to_use" instead of "bricks_used". In regression test, we found that priv->du_stat[0].chunks was zero. In this case "bricks_used" variable will be zero, which will cause crash for chunk = ((unsigned long) 0xffffffff) / bricks__used; calculation.
