This LWN article explains the why scnprintf is preferred over snprintf in general https://lwn.net/Articles/69419/ Ie. snprintf() returns what *would* be the resulting length, while scnprintf() returns the actual length. Note that ctcm_print_statistics() writes the data into the kernel log and is therefore not suitable for sysfs_emit(). Observable behavior is not changed, as there may be dependencies.
