Can you please explain why a feature like IMA that no sane user would ever want should cause _any_ overhead for users that just have it compiled in because their distro or defconfig did without actually using. What exactly is the problem to require the few people that want it to use a kernel command line option and/or an _DEFAULT_ON config option?
