I think the problem is, this adds an API between mm and balloon device that is pretty complex: consider that previously we literally only used alloc_page, __free_page and page->lru field. So you end up with a problem: mm bits don't do anything by themselves so mm people aren't very interested and don't know about virtio anyway, while we virtio device driver people lack a clue about compaction. Having said that I think I'm getting my head about some of the issues so I commented and the patchset is hopefully getting there. -- MST -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
