All it takes is a quick review and test ;) I think mspec was already tested, but it wouldn't hurt to verify again... It shaves about .5K off mm/memory.o so it is pretty significant. Mispredicted branches are also actually a significant cost in the fault path which I'm trying to reduce (merging fault with page_mkwrite should help with this further). -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
