This is a convenience given to rt_task() to reduce latency when possible by avoiding direct reclaim and allowing background reclaim to bring us back over the low watermark. That's been in the page allocator for over four years and is not intended to implement realtime behavior. These tasks do not rely on memory reserves being available. Is it really hard to believe that tasks with such high priorities are given an exemption in the page allocator so that we reclaim in the background instead of directly? I hope we can move this to another thread if people would like to remove this exemption completely instead of talking about this trivial fix, which I doubt there's any objection to. -- To unsubscribe from this list: send the line "unsubscribe kernel-testers" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
