yup, it's monday

>Description:
in cgd_modcmd:
case MODULE_CMD_INIT:
cgdattach(4);
return devsw_attach("cgd", &cgd_bdevsw, &bmajor,
&cgd_cdevsw, &cmajor);
break;
case MODULE_CMD_FINI:
return devsw_detach(&cgd_bdevsw, &cgd_cdevsw);
break;
I cannot find where cgdattach() is undone. If it is done through
a non-obvious hyperspace pointer maneuver, the resource releasing
code is indeed very well hidden.
