Nice.
I wonder if that can be even more simplified with
the following existing seq helpers:

extern struct list_head *seq_list_start(struct list_head *head,
		loff_t pos);
extern struct list_head *seq_list_start_head(struct list_head *head,
		loff_t pos);
extern struct list_head *seq_list_next(void *v, struct list_head *head,
		loff_t *ppos);


That said, it's already a nice cleanup.
