68 | * of both the head and tail pointers. The list is slightly unusual in that |
69 | * a parent-dir's content can be appended to the end of the local list in a | |
70 | * special way: the last item in the local list has its "next" pointer set | |
71 | * to point to the inherited list, but the local list's tail pointer points | |
72 | * at the end of the local list. Thus, if the local list is empty, the head | |
73 | * will be pointing at the inherited content but the tail will be NULL. To | |
74 | * help you visualize this, here are the possible list arrangements: | |
75 | * | |
76 | * Completely Empty Local Content Only | |
77 | * ================================== ==================================== | |
78 | * head -> NULL head -> Local1 -> Local2 -> NULL | |
79 | * tail -> NULL tail -------------^ | |
80 | * | |
81 | * Inherited Content Only Both Local and Inherited Content | |
82 | * ================================== ==================================== | |
83 | * head -> Parent1 -> Parent2 -> NULL head -> L1 -> L2 -> P1 -> P2 -> NULL | |
84 | * tail -> NULL tail ---------^ | |
85 | * | |
86 | * This means that anyone wanting to traverse the whole list to use it just | |
87 | * needs to start at the head and use the "next" pointers until it goes | |
88 | * NULL. To add new local content, we insert the item after the tail item | |
89 | * and update the tail (obviously, if "tail" was NULL, we insert it at the | |
90 | * head). To clear the local list, WE MUST NOT FREE THE INHERITED CONTENT | |
91 | * because it is shared between the current list and our parent list(s). | |
92 | * The easiest way to handle this is to simply truncate the list after the | |
93 | * tail item and then free the local list from the head. When inheriting | |
7842418b | 94 | * the list for a new local dir, we just save off the filter_list_struct |
6dfd07d0 WD |
95 | * values (so we can pop back to them later) and set the tail to NULL. |
