Steve,
Here is an initial set of patches that starts moving SMB2 PDU definitions
from the client/server into a shared smb2pd.h file.
It moves the command opcode values into cifs_common,
it renames cifs smb2_sync_hdr to smb2_hdr to harmonize with ksmbd naming
and it moves the tree connect and disconnect PDU definitions to the shared
file.

Create a share smb2pdu.h file and share it between the cifs client and server.
Start by moving the definition of opcode values into this shared
file.

The smbfsctl.h should also be easy to move ... but the obvious
question is whether "common" headers belong in "fs/cifs_common" or in
include/linux ...
(as e.g. nfs does with common headers between server and client)

Maybe. I think things that should never be used by any other,
non-cifs, modules might be better in cifs-common than make
them world visible in include/linux.
Especially things like pdu structures that should never be used by any
other modules.
But I do not feel strongly about it so feel free to git mv the file over there.
