I think you're confusing the two different linked lists - there's ki_run_list, which isn't used anymore after this patch (and deleted here), and ki_list, which is used for cancellation. Yeah, it's tricky and ugly. -- 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/
