> * MAC labels -- in-kernel storage format.

> * In general, struct label pointers are embedded in kernel data structures
> * representing objects that may be labeled (and protected). Struct label is
> * opaque to both kernel services that invoke the MAC Framework and MAC
> * policy modules. In particular, we do not wish to encode the layout of the
> * label structure into any ABIs. Historically, the slot array contained
> * unions of {long, void} but now contains uintptr_t.
