+ * struct bar {

+ * struct list_head list_of_foos;
+ * ...
+ * }
+ *
+ * struct foo {
+ * ...
+ * struct list_head entry;

+ * Now we initialize the list head:
+ *
+ * struct bar bar;
+ * ...
+ * INIT_LIST_HEAD(&bar.list_of_foos);

+ * struct foo *foo = malloc(...);
+ * ....
+ * list_add(&foo->entry, &bar.list_of_foos);
+ *
+ * Repeat the above for each element you want to add to the list. Deleting
+ * works with the element itself.
+ * list_del(&foo->entry);
+ * free(foo);
+ *
+ * Note: calling list_del(&bar.list_of_foos) will set bar.list_of_foos to an empty
