  /* IOCTL information */
  /*
   * List of ioctl/fsctl function codes that are or could be useful in the
   * future to remote clients like cifs or SMB2/SMB3 client.  This is probably
   * a slightly larger set of fsctls that NTFS local filesystem could handle,
   * including the seven below that we do not have struct definitions for.
   * Even with protocol definitions for most of these now available, we still
   * need to do some experimentation to identify which are practical to do
   * remotely.  Some of the following, such as the encryption/compression ones
   * could be invoked from tools via a specialized hook into the VFS rather
   * than via the standard vfs entry points
   *
   * See MS-SMB2 Section 2.2.31 (last checked June 2013, all of that list are
   * below). Additional detail on less common ones can be found in MS-FSCC
   * section 2.3.
