Of course, that change means that we wouldn't be able to throttle page allocators against IO any more, and we'd have to do something smarter. What a shame ;)This is actually necessary IMHO. Some testing I've been able to do seems to reveal the current throttling mechanism as inadequate.I don't think so. If you're referring to the situation where your 4G machine had 3.5G dirty pages without triggering writeback. That's not a generic problem.
But it is, mmap() and anonymous memory don't trigger writeback. regards, Rik -- Bravely reimplemented by the knights who say "NIH". http://www.surriel.com/ http://distro.conectiva.com/ -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
