Linux 2.6内核启动传递命令行的过程分析

__module_param_call("",nousb,param_set_bool,param_get_bool,&nousb,0444);
__module_param_call这个宏定义在kernel\include\linux\moduleparam.h

#define __module_param_call(prefix, name, set, get, arg, perm)  \
 static char __param_str_##name[] = prefix #name;  \
 static struct kernel_param const __param_##name   \
 __attribute_used__      \
    __attribute__ ((unused,__section__ ("__param"),aligned(sizeof(void *)))) \
 = { __param_str_##name, perm, set, get, arg }
