In tree-log.c:btrfs_log_inode(), we keep calling btrfs_search_forward() until it returns a key whose objectid is higher than our inode or until the key's type is higher than our maximum allowed type.
At the end of the loop, we increment our mininum search key's objectid and type regardless of our desired target objectid and maximum desired type, which causes another loop iteration that will call again btrfs_search_forward() just to figure out we've gone beyond our maximum key and exit the loop. Therefore while incrementing our minimum key, don't do it blindly and exit the loop immiediately if the next search key's objectid or type is beyond what we seek.
