  * This code tests if the attributes field of statx received expected value.
  * File set with following flags by using SAFE_IOCTL:
- * 1) STATX_ATTR_COMPRESSED - The file is compressed by the filesystem.
- * 2) STATX_ATTR_IMMUTABLE - The file cannot be modified.
- * 3) STATX_ATTR_APPEND - The file can only be opened in append mode for
- *                        writing.
- * 4) STATX_ATTR_NODUMP - File is not a candidate for backup when a backup

  *                        program such as dump(8) is run.
