A side effect of this is that the small pieces of code in drivers/of have to be compiled into stand alone modules and they may need access to internal symbols from the subsystem. If they were directly linked into the subsystems you wouldn't need to make the internal symbols visible. Now the subsystems have to be careful about breaking the in-kernel, external users of the symbols and we've made it possible for out of tree drivers to get to internal structures. > > -- > > Jean Delvare > -- Jon Smirl [EMAIL PROTECTED] _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev
