Example: Module Representation in the Kernel (5)
Code that produces module dependency: a uses b
Module a is the source and module b is the target
int add_module_usage(struct module *a, *b)
{
struct module_use *use;
use = kmalloc(sizeof(struct module_use),GFP_ATOMIC);
if (!use)
return ­ENOMEM;
use­>source = a; use­>target = b;
list_add(&use­>source_list, &b­>source_list);
list_add(&use­>target_list, &a­>target_list);
return 0;
}
