 * Name: statvfs
 *
 * Description:
 *   The statvfs() function shall obtain information about the file system
 *   containing the file named by path.

 *   required.
 *
 * Returned Value:
 *   Upon successful completion, statvfs() shall return 0. Otherwise, it
 *   shall return -1 and set errno to indicate the error.
