I don't understand that. Debug options do changes in object layout. Since they add significant performance overhead and cannot be undone in runtime it's unlikely that anyone who uses them don't care about merging after that. Also I don't see how merging could affect debugging in positive way (except debugging bugs in merging logic itself). -- 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/
