Doesn't this have to > happen as part of migrate_pages()? You might want to change it, but it's a pure policy issue. And such kind of policy should be in user space. However I can see it being ugly to grab the list of policies from user space (it would need a /proc file). Perhaps you're right and it's better to do in the kernel. It just won't be very pretty code to convert all the masks. -Andi -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
