I took it from here:
https://git.samba.org/?p=metze/linux/smbdirect.git;a=blob;f=smbdirect_private.h;hb=284ad8ea768c06e3cc70d6f2754929a6abbd2719

In the end smbdirect.h will be the only header used outside
of fs/smb/common/smbdirect, it will be the public api, to be used
by the smb layer.

smbdirect_pdu.h holds protocol definitions, while smbdirect_socket.h
will be some kind of internal header that holds structures shared between multiple .c files.

But we'll see I think this is a start in the correct direction.

I try to focus on doing tiny steps avoiding doing to much at the same time
or even try to avoid thinking about the next step already...
