+Subject: [PATCH] fix unsigned integer subtraction sign overflow
+
+Min_load, adjustment_load  and load are unsigned integers, so it overflows when (lb_info->min_load + info->load) < (lb_info->adjustment_load - info->load). The result will be greater than zero. Therefore the irq cannot be selected to rebalanced.
