Probably. But your patch doesn;t gain them anything but a useless
ifdef.. Look at include/linux/genhd.h:
#ifdef CONFIG_BLK_STATS
extern void disk_round_stats(struct hd_struct *hd);
extern void req_new_io(struct request *req, int merge, int sectors);
extern void req_merged_io(struct request *req);
extern void req_finished_io(struct request *req);
#else
static inline void req_new_io(struct request *req, int merge, int sectors) { }
static inline void req_merged_io(struct request *req) { }
static inline void req_finished_io(struct request *req) { }
#endif /* CONFIG_BLK_STATS */
