AU_BUILTIN_MAX

#define AU_BUILTIN_MAX   8

Registry of drivers that are linked into the kernel but can still be handed over: a built-in driver registers the PCI function it bound, plus how to let go of it (release) and how to take it back (reinit). That makes them behave like loadable drivers for /dev/drvctl ("unload NAME" / "load NAME") and lets /dev/hwdev refuse a PCI function a built-in driver still owns, which is what allows a user-space server to take such a device over safely and the supervisor to give it back.
