   * Name: statvfs
   *
   * Description:
   *   The statvfs() function shall obtain information about the file system
   *   containing the file named by path.
   *
   *   the buf argument is a pointer to a statvfs structure that shall be
   *   filled. Read, write, or execute permission of the named file is not
   *   required.
   *
   * Returned Value:
   *   Upon successful completion, statvfs() shall return 0. Otherwise, it
   *   shall return -1 and set errno to indicate the error.
