(

ptr

)

Value:

} 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.

static void list_add	(	struct list_head *	new_lh,
		struct list_head *	head
	)			[inline, static]

list_add - add a new entry : new entry to be added : list head to add it after

Insert a new entry after the specified head. This is good for implementing stacks.

static void list_add_tail	(	struct list_head *	new_lh,
		struct list_head *	head
	)			[inline, static]

list_add_tail - add a new entry : new entry to be added : list head to add it before

Insert a new entry before the specified head. This is useful for implementing queues.

static void list_del

(

struct list_head *

entry

)

[inline, static]

list_del - deletes entry from list. : the element to delete from the list. Note: list_empty on entry does not return true after this, the entry is in an undefined state.

static void list_del_init

(

struct list_head *

entry

)

[inline, static]

list_del_init - deletes entry from list and reinitialize it. : the element to delete from the list.

static int list_empty

(

struct list_head *

head

)

[inline, static]

list_empty - tests whether a list is empty : the list to test.

static void list_move	(	struct list_head *	list,
		struct list_head *	head
	)			[inline, static]

list_move - delete from one list and add as another's head : the entry to move : the head that will precede our entry

static void list_move_tail	(	struct list_head *	list,
		struct list_head *	head
	)			[inline, static]

list_move_tail - delete from one list and add as another's tail : the entry to move : the head that will follow our entry

static void list_splice	(	struct list_head *	list,
		struct list_head *	head
	)			[inline, static]

list_splice - join two lists : the new list to add. : the place to add it in the first list.

static void list_splice_init	(	struct list_head *	list,
		struct list_head *	head
	)			[inline, static]

list_splice_init - join two lists and reinitialise the emptied list. : the new list to add. : the place to add it in the first list.

The list at is reinitialised
