+ * 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 September 2021, all of that list are
+ * below). Additional detail on less common ones can be found in MS-FSCC
+ * section 2.3.
