Yes, we used this term in the LSM overview document to refer to the
security module registered via the top-level register_security function.
The top-level register_security function only permits one such module to
be registered at any given time.  Since this module is ultimately
responsible for handling the hooks and for handling any stacking of
subsequent modules, we referred to it as "primary".  In practice, this
means the first loaded/initialized security module, although another
module could later become primary if the first module calls
unregister_security.
