We're basically handing down a proper function pointer to call and at module unload time we clear it. Also, those register/unregister functions could be made to return an errval so that code calling them can handle that gracefully. Bottom line is, IMO we're much better off having a clearly defined interface like that instead of exporting a naked function pointer. Thoughts? -- Regards/Gruss, Boris.
