/* IOCTL information */
/*
* 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.
