-    Each VFS module must provide following global functions:
-    vfs_init	-- initialization function
-    vfs_done	-- finalization function
-    
-    vfs_init must return proper initialized vfs_op_tuple[] array
-    which describes all operations this module claims to intercept. This function
-    is called whenever module is loaded into smbd process using sys_dlopen().
-    
-    vfs_init must store somewhere vfs_handle reference if module wants to store per-instance
-    private information for further usage. vfs_handle->data should be used to
-    store such information. Do not try to change other fields in this structure
-    or results likely to be unpredictable.
-    
-    vfs_done must perform finalization of the module. In particular,
-    this function must free vfs_ops structure returned to module from smb_vfs_get_opaque_ops()
-    function if it is used (see below). This function is called whenever module 
-    is unloaded from smbd process using sys_dlclose().
-    
-    Prototypes:
-    vfs_op_tuple *vfs_init(const struct vfs_ops *def_vfs_ops,
-			    struct smb_vfs_handle_struct *vfs_handle);
-    void	  vfs_done(connection_struct *conn);
-

-    in order to keep smbd namespace unpolluted. See source of skel, audit, and recycle bin
