What about rest cases?

â  kernel git:(rdma-next) git grep "sg++" net/rds/
net/rds/message.c:              sg++;
net/rds/message.c:                      sg++;
net/rds/message.c:                      sg++;
net/rds/send.c:                                 sg++;
net/rds/tcp_send.c:                     sg++;

Thanks
