22 /* IOCTL information */
23 /*
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.
