On s390 we currently don't do anything suspend related at all - I'd need to think about that. (I use device_move() to reflect topology changes on the (virtual) hardware, so I'd guess the "don't suspend parent before child rule" should still apply afterwards. But of course, that also depends on what we actually need to do on the parent's bus and what on the child's bus.) -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
