| | 24 | * List of ioctl/fsctl function codes that are or could be useful in the |
| | 25 | * future to remote clients like cifs or SMB2/SMB3 client. This is probably |
| | 26 | * a slightly larger set of fsctls that NTFS local filesystem could handle, |
| | 27 | * including the seven below that we do not have struct definitions for. |
| | 28 | * Even with protocol definitions for most of these now available, we still |
| | 29 | * need to do some experimentation to identify which are practical to do |
| | 30 | * remotely. Some of the following, such as the encryption/compression ones |
| | 31 | * could be invoked from tools via a specialized hook into the VFS rather |
| | 32 | * than via the standard vfs entry points |
| | 33 | * |
| | 34 | * See MS-SMB2 Section 2.2.31 (last checked June 2013, all of that list are |
| | 35 | * below). Additional detail on less common ones can be found in MS-FSCC |
| | 36 | * section 2.3. |
