I see it fallbacks to 4k instead of gradually going down, but that was my point, doing the fallback and entry alloc_pages N without internal buddy support would be fairly inefficient. This is why is suggest this logic to be outside of slab/slub, in theory even slab could be a bit faster thanks to large TLB on newly allocated slab objects. I hope Mel's code already takes care of all of this. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxxx For more info on Linux MM, see: http://www.linux-mm.org/ .
