Subject: cifs: remove unused SMB2 config and mount options
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=c02324a6ae6bd3e83533c59525111ffe03b7e791;p=linux-beck.git

cifs: remove unused SMB2 config and mount options

There's no SMB2 support in the CIFS filesystem driver, so there's no need to
have a config and mount option for it.
