描述性宏定义

内核代码中有一个描述性质的宏定义，它们会有出现在modinfo命令的打印结果里。

modinfo netconsole.ko
filename:       netconsole.ko
license:        GPL
description:    Console driver for network interfaces

srcversion:     4771B517D075072C76D13FE
depends:        configfs
intree:         Y
vermagic:       3.2.0-29-generic SMP mod_unload modversions
parm:           netconsole:
netconsole=[src-port]@[src-ip]/[dev],[tgt-port]@<tgt-ip>/[tgt-macaddr] (string)

modinfo macvlan.ko
filename:       macvlan.ko
alias:          rtnl-link-macvlan
description:    Driver for MAC address based VLANs

vermagic:       3.2.0-29-generic SMP mod_unload modversions

version:        3.5.24-k2-NAPI
  

上述显示的内容分别由以下宏定义产生：

author:

MODULE_AUTHOR("xxxxx")
  

description:

MODULE_DESCRIPTION("yyyyyyyyyyyy");
  

license:

MODULE_LICENSE("GPL");
  

alias:

MODULE_ALIAS("alternate_name");
  

version:

MODULE_VERSION(version_string)
  

parm:

static char *string_test = "this is a test";
static num_test = 1000;
module_param (num_test,int,S_IRUGO);
module_param (string_test,charp,S_ITUGO);
  

#if LINUX_VERSION_CODE>=KERNULVERSION(2.4.9)
