--- Comment #4 from Willy Tarreau <w at 1wt dot eu> --- Hi Martin, I'm sorry but I'm missing something, as this is how linked lists are implemented everywhere nowadays. I'm not actually casting the pointer, it was made for simplification. I'm only following the list elements which are linked together from a list head accessed via a container_of. The code does nothing but follow the list from the head (which is only a struct list) and visiting all nodes in turn. There is absolutely zero dereference of a list using a wrong pointer here.
