[linux-cifs-client] Re: Howto build cifs module kernel only

[Steven French]

If you are updating an existing cifs.ko (cifs is usually built by default 
as a module) in /lib/modules ... - then you should not need to update 
depmod but if you want the cifs module in a different directory to be 
loaded automatically it may be helpful

And what about running depmod? Isn't it required?

I wrote an article with all this in here:
