No, soft offlining can still allow accesses for some time. It'll never kill anything. Hard tries much harder and will kill. In some cases (unshrinkable kernel allocation) they end up doing the same because there isn't any other alternative though. However these are expected to only apply to a small percentage of pages in a typical system. -Andi -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
