This is somewhat longer that necessary.
struct llist_node *llist_reverse_order(struct llist_node *head)
{
struct llist_node *new_head = NULL;
while (head) {
struct llist_node *tmp = head;
head = head->next;
tmp->next = new_head;
new_head = tmp;
}
return new_head;
}
I think that is short enough to just open-code in the top of
release_stripe_list.
Are you OK with that?
