11 * List of ioctl/fsctl function codes that are or could be useful in the
12 * future to remote clients like cifs or SMB2 client.  There is probably
13 * a slightly larger set of fsctls that NTFS local filesystem could handle,
14 * including the seven below that we do not have struct definitions for.
15 * Even with protocol definitions for most of these now available, we still
16 * need to do some experimentation to identify which are practical to do
17 * remotely.  Some of the following, such as the encryption/compression ones
18 * could be invoked from tools via a specialized hook into the VFS rather
19 * than via the standard vfs entry points
