cifs: no need to use rcu_assign_pointer on immutable keys
cifs: no need to use rcu_assign_pointer on immutable keys Neither keytype in use by CIFS has an "update" method. This means that the keys are immutable once instantiated. We don't need to use RCU to set the payload data pointers. Signed-off-by: Jeff Layton <jlayton@redhat.com> Signed-off-by: Steve French <sfrench@us.ibm.com>
