    14.

    15. 

  15.  * including the seven below that we do not have struct definitions for.
    16. 

  16.  * Even with protocol definitions for most of these now available, we still
    17. 

  17.  * need to do some experimentation to identify which are practical to do
    18. 

  18.  * remotely.  Some of the following, such as the encryption/compression ones
    19. 

  19.  * could be invoked from tools via a specialized hook into the VFS rather
    20. 

  20.  * than via the standard vfs entry points
    21.
