  22/* IOCTL information */
  23/*
  24 * List of ioctl/fsctl function codes that are or could be useful in the
  25 * future to remote clients like cifs or SMB2 client.  There is probably
  26 * a slightly larger set of fsctls that NTFS local filesystem could handle,
  27 * including the seven below that we do not have struct definitions for.
  28 * Even with protocol definitions for most of these now available, we still
  29 * need to do some experimentation to identify which are practical to do
  30 * remotely.  Some of the following, such as the encryption/compression ones
  31 * could be invoked from tools via a specialized hook into the VFS rather
  32 * than via the standard vfs entry points
