## Define Documentation

#define INIT_LIST_HEAD | ( | ptr |  | ) |

Value:

    do { \
            (ptr)->next = (ptr); (ptr)->prev = (ptr); \
    } while (0)

#define list_entry | ( | ptr,
|  | type,
|  | member |  | ) | ((type *)((char *)(ptr)-(unsigned long)(&((type *)0)->member)))

list_entry - get the struct for this entry : the &struct list_head pointer. : the type of the struct this is embedded in. : the name of the list_struct within the struct.

#define list_for_each | ( | pos,
|  | head |  | ) |

Value:

    for (pos = (head)->next; pos != (head); \
                    pos = pos->next)

list_for_each - iterate over a list : the &struct list_head to use as a loop counter. : the head for your list.

#define list_for_each_entry | ( | pos,
|  | head,
|  | member |  | ) |

Value:

    for (pos = list_entry((head)->next, typeof(*pos), member);      \
                 &pos->member != (head);                                    \
                 pos = list_entry(pos->member.next, typeof(*pos), member))

list_for_each_entry - iterate over list of given type : the type * to use as a loop counter. : the head for your list. : the name of the list_struct within the struct.

#define list_for_each_entry_safe | ( | pos,
|  | n,
|  | head,
|  | member |  | ) |

Value:

    for (pos = list_entry((head)->next, typeof(*pos), member),      \
                    n = list_entry(pos->member.next, typeof(*pos), member); \
                 &pos->member != (head);                                    \
                 pos = n, n = list_entry(n->member.next, typeof(*n), member))

list_for_each_entry_safe - iterate over list of given type safe against removal of list entry : the type * to use as a loop counter.
: another type * to use as temporary storage : the head for your list. : the name of the list_struct within the struct.

#define list_for_each_prev | ( | pos,
|  | head |  | ) |

Value:

    for (pos = (head)->prev; pos != (head); \
                    pos = pos->prev)

list_for_each_prev - iterate over a list backwards : the &struct list_head to use as a loop counter. : the head for your list.

#define list_for_each_safe | ( | pos,
|  | n,
|  | head |  | ) |

Value:

    for (pos = (head)->next, n = pos->next; pos != (head); \
                    pos = n, n = pos->next)

list_for_each_safe - iterate over a list safe against removal of list entry : the &struct list_head to use as a loop counter.
: another &struct list_head to use as temporary storage : the head for your list.

#define LIST_HEAD | ( | name |  | ) | struct list_head name = LIST_HEAD_INIT(name)

#define LIST_HEAD_INIT | ( | name |  | ) | { &(name), &(name) }
