Subject: NFSv4.1: Always set up a forward channel when binding the session
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=7e9f07388779ccc5067f206357d9791aeef38864;p=linux-beck.git

NFSv4.1: Always set up a forward channel when binding the session

Currently, the client requests a back channel or a bidirectional
connection when binding a new TCP channel to an existing session.
Fix that to ask for a forward channel or bidirectional.
