{ &(name), &(name) }

list_entry

#define list_entry	(		ptr,
			type,

list_entry - get the struct for this entry

Parameters

ptr	the &struct list_head pointer.
type	the type of the struct this is embedded in.
member	the name of the list_struct within the struct.

list_for_each

        pos = pos->next)

list_for_each - iterate over a list

Parameters

pos	the &struct list_head to use as a loop counter.
head	the head for your list.
