Add missing structure definition for various newer fsctl operations
- duplicate_extents_ex
- get_integrity_information
- query_file_regions
- query_on_disk_volume_info
And move some fsctl defintions to smbfs_common

smbfs_common
Fix an endian bug in ksmbd for one remaining use of
Persistent/VolatileFid that unnecessarily converted it (it is an
opaque endian field that does not need to be and should not
be converted) in oplock_break for ksmbd, and move the definitions
for the oplock and lease break protocol requests and responses
to fs/smbfs_common/smb2pdu.h
Also move a few more definitions for various protocol requests
that were duplicated (in fs/cifs/smb2pdu.h and fs/ksmbd/smb2pdu.h)
into fs/smbfs_common/smb2pdu.h including:
- various ioctls and reparse structures
- validate negotiate request and response structs
- duplicate extents structs

Includes moving to common code (from cifs and ksmbd protocol related
headers)
- query and query directory info levels and structs
- set info structs
- SMB2 lock struct and flags
- SMB2 echo req
Also shorten a few flag names (e.g. SMB2_LOCKFLAG_EXCLUSIVE_LOCK
to SMB2_LOCKFLAG_EXCLUSIVE)

The definitions for the ioctl SMB3 request and response as well
as length of various fields defined in the protocol documentation
were duplicated in fs/ksmbd and fs/cifs. Move these to the common
code in fs/smbfs_common/smb2pdu.h

We have duplicated definitions for various SMB3 PDUs in
fs/ksmbd and fs/cifs. Some had already been moved to
fs/smbfs_common/smb2pdu.h
Move definitions for
- error response
- query info and various related protocol flags
- various lease handling flags and the create lease context
to smbfs_common/smb2pdu.h to reduce code duplication

The client used to partially convert the fids to le64, while storing
or sending them by using host endianness. This broke the client on
big-endian machines. Instead of converting them to le64, store them
as opaque integers and then avoid byteswapping when sending them over
wire.

In the October updates to MS-SMB2 two additional FSCTLs
were described. Add the missing defines for these,
as well as fix a typo in an earlier define.

The exit function is wrongly placed in the __init section and this leads
to a crash when the module is unloaded. Just remove both the init and
exit functions since this module does not need them.

This file will contain all the definitions we need for SMB2 packets
and will follow the naming convention of MS-SMB2.PDF as closely
as possible to make it easier to cross-reference beween the definitions
and the standard.
The content of this file will mostly consist of migration of existing
definitions in the cifs/smb2.pdu.h and ksmbd/smb2pdu.h files
with some additional tweaks as the two files have diverged.
This patch introduces the new smbfs_common/smb2pdu.h file
and migrates the SMB2 header as well as TREE_CONNECT and TREE_DISCONNECT
to the shared file.

checkpatch complains about source files with filenames (e.g. in
these cases just below the SPDX header in comments at the top of
various files in fs/cifs). It also is helpful to change this now
so will be less confusing when the parent directory is renamed
e.g. from fs/cifs to fs/smb_client (or fs/smbfs)

The FSCTL definitions are in smbfsctl.h which should be
shared by client and server. Move the updated version of
smbfsctl.h into smbfs_common and have the client code use
it (subsequent patch will change the server to use this
common version of the header).

As we move to common code between client and server, we have
been asked to make the names less confusing, and refer less
to "cifs" and more to words which include "smb" instead to
e.g. "smbfs" for the client (we already have "ksmbd" for the
kernel server, and "smbd" for the user space Samba daemon).
So to be more consistent in the naming of common code between
client and server and reduce the risk of merge conflicts as
more common code is added - rename "cifs_common" to
"smbfs_common" (in future releases we also will rename
the fs/cifs directory to fs/smbfs)
