[PATCH] mount.cifs: don't send a mandatory ver= option to the kernel

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Traditionally, this ver= option was used to specify the "options
version" that we're passing in. It has always been set to '1' though
and we have never changed that.

Eventually we want to have a ver= (or vers=) option that allows users
to specify the SMB version that they want to use to talk to the server.

At that point, this option will just get in the way. Let's go ahead
and remove it now in preparation for that day.
