samba - Jul 2015 - cifs.ko kernel module versus smb.conf - which SMB protocol version?

Hello guys,
could someone help me better understand the mechanism of negotiating of 
the SMB protocol?

I watch closely samba list and recently there was a talk about the 
'smb.conf' parameters like eg. "max protocol =" etc. with
regards to
Windows 10 (and other windows clients of diff versions).

I read Jeff_Layton-Linux-CIFS-Client.pdf and

https://wiki.samba.org/index.php/SMB3_kernel_status

My question is:
1. does those parameters values (like 'max protocol') depend on the 
'cifs.ko' version and it's supported SMB version? Meaning it's
pointless
to set higher SMB value in smb.conf that the 'cifs.ko' support?

2. does samba server use the 'cifs.ko' to access linux (eg. ext4 of xfs 
FS) to serve the windows client requests?

Sorry if those questions might seam stupid to someone, i'm just mere 
admin trying to get better understanding of this mechanism.

Thank You

no - why should it?
the "mount.cifs" command has little to do with samba itself

https://www.kernel.org/doc/readme/Documentation-filesystems-cifs-README

[root at fileserver:~]$ locate cifs.ko
/usr/lib/modules/4.0.6-200.fc21.x86_64/kernel/fs/cifs/cifs.ko.xz
[root at fileserver:~]$ lsmod | grep cifs

Samba (smbd) is a CIFS server.  cifs.ko is a CIFS client.  There is no 
relation between the two other than that you can use cifs.ko to connect to 
a samba server.

thank you for kind explanation :]
