| /* |
| * 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 June 2013, all of that list are |
| * below). Additional detail on less common ones can be found in MS-FSCC |
| * section 2.3. |
