IMHO a restriction of access to slab statistics is reasonable in a
hardened environment. Make it dependent on CONFIG_SECURITY or some such
thing?

Probably need to invent a separate Kconfig variable - CONFIG_SECURITY
is probably a way-too-big hammer for this nail. I can see lots of systems
that want to enable that, but won't want to tighten access to slab.

There is already CONFIG_SECURITY_DMESG_RESTRICT. Generalize that setting
to include all sorts of other kernel statistics?
