I'm not sure I understand what you mean. You can pick a recent vanilla
kernel or rebuild your distro kernel with these options enabled (they
have been there for a while). There is no patch to apply. You might be
able to check the options built in your current kernel by looking at
/proc/config.gz, they might already be enabled.

Historically cifs.ko was a samba project. Both have a (neglected :(...)
cifs section you can use.

The Samba server lets you pick the min and max supported protocols via
"server min protocol" and "server max protocol" in smb.conf. Look at
your smb.conf man page for possible values supported by your system
smbd.

(I'm assuming you meant "the server is samba" as there is no in-kernel
cifs server that I know of)

Windows clients will try to negotiate the highest protocol version but
cifs.ko defaults to 1.0 unless you specify otherwise via -o vers=xyz at
mount.
