#define container_of	(		ptr,
			type,
			member
	)

Value:

({                      \
    const typeof( ((type *)0)->member ) *__mptr = (ptr);    \
    (type *)( (char *)__mptr - offsetof(type,member) );})

container_of - cast a member of a structure out to the containing structure : the pointer to the member. : the type of the container struct this is embedded in. : the name of the member within the struct.

Definition at line 18 of file list.h.

#define list_entry	(		ptr,
			type,
			member
	)		container_of(ptr, type, 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.

Definition at line 39 of file list.h.

#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 cursor. : the head for your list. : the name of the list_struct within the struct.
