-/**
- * @file Classic doubly-link circular list implementation.
- * For real usage examples of the linked list, see the file test/list.c
- *
- * Example:
- * We need to keep a list of struct foo in the parent struct bar, i.e. what
- * we want is something like this.
- *
- *     struct bar {
- *          ...
- *          struct foo *list_of_foos; -----> struct foo {}, struct foo {}, struct foo{}
- *          ...
- *     }
- *
- * We need one list head in bar and a list element in all list_of_foos (both are of
- * data type 'struct list_head').
- *
- *     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);
- *
- * Then we create the first element and add it to this list:
- *
- *     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
- * list again.
- *
- * Looping through the list requires a 'struct foo' as iterator and the
- * name of the field the subnodes use.
- *
- * struct foo *iterator;
- * list_for_each_entry(iterator, &bar.list_of_foos, entry) {
- *      if (iterator->something == ...)
- *             ...
- * }
- *
- * Note: You must not call list_del() on the iterator if you continue the
- * loop. You need to run the safe for-each loop instead:
- *
- * struct foo *iterator, *next;
- * list_for_each_entry_safe(iterator, next, &bar.list_of_foos, entry) {
- *      if (...)
- *              list_del(&iterator->entry);
- * }
- *

-/**
- * The linkage struct for list nodes. This struct must be part of your
- * to-be-linked struct. struct list_head is required for both the head of the
- * list and for each list node.

- * There are no requirements that elements of a list are of the same type.
- * There are no requirements for a list head, any struct list_head can be a list
