67 * a parent-dir's content can be appended to the end of the local list in a
68 * special way: the last item in the local list has its "next" pointer set
69 * to point to the inherited list, but the local list's tail pointer points
70 * at the end of the local list. Thus, if the local list is empty, the head
71 * will be pointing at the inherited content but the tail will be NULL. To
72 * help you visualize this, here are the possible list arrangements:
74 * Completely Empty Local Content Only
75 * ================================== ====================================
76 * head -> NULL head -> Local1 -> Local2 -> NULL
77 * tail -> NULL tail -------------^
79 * Inherited Content Only Both Local and Inherited Content
80 * ================================== ====================================
81 * head -> Parent1 -> Parent2 -> NULL head -> L1 -> L2 -> P1 -> P2 -> NULL
82 * tail -> NULL tail ---------^
84 * This means that anyone wanting to traverse the whole list to use it just
85 * needs to start at the head and use the "next" pointers until it goes
86 * NULL. To add new local content, we insert the item after the tail item
87 * and update the tail (obviously, if "tail" was NULL, we insert it at the
88 * head). To clear the local list, WE MUST NOT FREE THE INHERITED CONTENT
89 * because it is shared between the current list and our parent list(s).
90 * The easiest way to handle this is to simply truncate the list after the
91 * tail item and then free the local list from the head. When inheriting
92 * the list for a new local dir, we just save off the exclude_list_struct
93 * values (so we can pop back to them later) and set the tail to NULL.
