The kernel is globally removing the ambiguous 0-length and 1-element
arrays in favor of flexible arrays, so that we can gain both compile-time
and run-time array bounds checking[1].
Replace the trailing 1-element array with a flexible array in the
following structures:
struct smb2_err_rsp
struct smb2_tree_connect_req
struct smb2_negotiate_rsp
struct smb2_sess_setup_req
struct smb2_sess_setup_rsp
struct smb2_read_req
struct smb2_read_rsp
struct smb2_write_req
struct smb2_write_rsp
struct smb2_query_directory_req
struct smb2_query_directory_rsp
struct smb2_set_info_req
struct smb2_change_notify_rsp
struct smb2_create_rsp
struct smb2_query_info_req
struct smb2_query_info_rsp
Replace the trailing 1-element array with a flexible array, but leave
the existing structure padding:
struct smb2_file_all_info
struct smb2_lock_req
Adjust all related size calculations to match the changes to sizeof().
No machine code output or .data section differences are produced after
these changes.

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)

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.

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.
