By looking at what they turn on? What happened to the good old idea
of actually auditing what you turn on? It might be a bit too much
for every little driver, aven if that was helpful, but for security/
code with intricate hooks all over the kernel I think it is in order.

Especially as our merge requirements for security/ are a lot lower than
for the rest of the kernel given that James is very afraid of getting
whacked by Linux for not mering things.
