The only major thing that's really missing, and which should help dramatically with the I/O patters is stopping direct writeback from balance_dirty_pages(). I've seen patches frrom Wu and and Jan for this and lots of discussion. If we get either variant in this should be once of the best VM release from the filesystem point of view. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
