This is the first chunk of SMB2 patches. It allows:
1) mount a network share,
2) stat inode information,
3) send echo message,
4) display statistics.
The patchset implements the approach of having ops structure of
protocol-specific callbacks that is used by the generic code.
Pavel Shilovsky (21):
CIFS: Add SMB2 status codes
CIFS: Make transport routines work with SMB2
CIFS: Add SMB2 credits support
CIFS: Make demultiplex_thread work with SMB2 code
CIFS: Respect SMB2 header/max header size
CIFS: Add capability to send SMB2 negotiate message
CIFS: Add session setup/logoff capability for SMB2
CIFS: Add tree connect/disconnect capability for SMB2
CIFS: Process reconnects for SMB2 shares
CIFS: Move getting dfs referalls to ops struct
CIFS: Move informational tcon calls to ops struct
CIFS: Move is_path_accessible to ops struct
CIFS: Add SMB2 support for is_path_accessible
CIFS: Move query inode info code to ops struct
CIFS: Query SMB2 inode info
CIFS: Move building path to root to ops struct
CIFS: Add SMB2 support for build_path_to_root
CIFS: Move echo code to osp struct
CIFS: Add echo request support for SMB2
CIFS: Move clear/print_stats code to ops struct
CIFS: Allow SMB2 statistics to be tracked

CIFS: Map SMB2 status codes to POSIX errors

For SMB2 protocol we can add more than one credit for one received
request: it depends on CreditRequest field in SMB2 response header.
Also we divide all requests by type: echos, oplocks and others. Each
type uses its own slot pull.

are bigger and suitable for both CIFS and SMB2.

Since there are only 19 command codes, it also is easier to track by exact
command code than it was for cifs.

Well, on the plus side, you did comment out STATUS_BUFFER_OVERFLOW
which was a definite conflict with the definitions in the SMB1 status
code list. However...I'm fairly certain that there are other conflicts
here, so that was just an example.
You really have two choices here:
1) make smb2status.h and nterr.h be mutually exclusive. Ensure that you
never #include both files. At first glance, this may be easy, but the
trick will be to ensure that no one does this in the future.
2) rename all of these error codes such that they do not conflict with
the SMB1 errors. This is more certain to ensure that you don't have
problems, but it's a bigger change.
I really don't care which one you choose, but we really do need to take
steps to ensure that we do not get conflicts here.

I know that this is bikeshedding, but there's little difference between
these names and the ones below. That is going to result in bugs when we
get these mixed up (and we will).
Perhaps you should give the ones above more distinct names --
SMB2_NEGOTIATE_HE or something? Where _HE means host-endian?

Would it be better to define this in terms of sizeof(SMB2_LARGEST_HEADER_STRUCT) ?

nterr.h has only 5 macros started with STATUS_:
#define STATUS_MORE_ENTRIES 0x0105
#define STATUS_1804>---- 0x070c
#define STATUS_NOTIFY_ENUM_DIR 0x010c
#define STATUS_SOME_UNMAPPED 0x0107
#define STATUS_BUFFER_OVERFLOW 0x80000005
I've already checked all them and commented dublicates in smb2status.h
(STATUS_MORE_ENTRIES, STATUS_NOTIFY_ENUM_DIR, STATUS_BUFFER_OVERFLOW)
- no conflicts now.
But I don't care to rename all error codes to something like
SMB2_STATUS_ to make sure we will not miss something in future.

Now we only define smb2_hdr structure - we can fix this value further

After a discussion with Jeff we came to the following rules:
1) prefix 7 error codes from nterr.h with NT_ that doesn't thave NT_
and consider them as CIFS codes.
2) consider codes from smb2status.h patch as new style codes (suitable
for SMB2, SMB2.1 and SMB3).

Yes - but also have to doublecheck that we didn't miss some new ones.
