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 */
