Please don't top-reply.
That is not true, the parameters are passed via 'uargs' of init_module() dynamically, this is when you invoke modprobe/insmod.
For your own kernel module, you may use module_param() to provide parameters, the max of this is limited to the size of ELF section size, since they are stored in "__param" section. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
