The fundamental problem with the 'standardized kernel tee' still
exists - it will never be generic in real life. Getting all this in
the kernel will solve your problem and sell this particular product,
but it is quite unlikely to help that many users. If the security is
truly important to you, would you really trust any of this code to
someone else? In this day and age, I really doubt many do. Everyone
does their own thing, so this is why I really see all that as a
userspace problem.
