Sorry, I have none. But you're unlikely to get your changes considered seriously unless you can avoid any new overhead your patch has which is of this level. We're busy trying to make these data structures smaller, and eliminate atomic operations, as much as possible. Therefore anything which adds new datastructure elements and new atomic operations will be met with fierce resistence unless it results an equal or greater shrink of datastructures elsewhere or removes atomic operations elsewhere in the critical path. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
