Dynamic method

The dynamic method consists of a struct list_head and initializes it with the INIT_LIST_HEAD macro:

struct list_head mylist; 
INIT_LIST_HEAD(&mylist); 

The following is the expansion of INIT_LIST_HEAD:

static inline void INIT_LIST_HEAD(struct list_head *list) 
   { 
       list->next = list; 
       list->prev = list; 
   }
