No, I didn't bother. Any current compilers already do make this assumption valid as it's been part of the c spec since 1989 and prototypes without extern already are the predominate form in .h files for linux kernel sources. Even in drivers/net/ethernet/intel/... there are more prototypes without extern than with extern. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
