- * container_of - routine for upcasting
- *
- * It is often convenient to create code where the caller registers a pointer
- * to a generic structure and a callback.  The callback might know that the
- * pointer points to within a larger structure, and container_of gives a
- * convenient and fairly type-safe way of returning to the enclosing structure.
- *
- * This idiom is an alternative to providing a void * pointer for every
- * callback.
- *
- * Example:
- *     struct info
- *     {
- *             int my_stuff;
- *             struct timer timer;
- *     };
- *
- *     static void my_timer_callback(struct timer *timer)
- *     {
- *             struct info *info = container_of(timer, struct info, timer);
- *             printf("my_stuff is %u\n", info->my_stuff);
- *     }
- *
- *     int main()
- *     {
- *             struct info info = { .my_stuff = 1 };
- *
- *             register_timer(&info.timer);
- *             ...

-int main(int argc, char *argv[])
-{
-       if (argc != 2)
-               return 1;
-
-       if (strcmp(argv[1], "depends") == 0) {
