CWE: CWE-22 \u2014 Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.

Code:
FIO_FUNC inline void fio_throttle_thread(size_t nano_sec) {
  const struct timespec tm = {.tv_nsec = (nano_sec % 1000000000),
                              .tv_sec = (nano_sec / 1000000000)};
  nanosleep(&tm, NULL);
}
