How to use SMB Direct

[Xiaoli Feng <xifeng@redhat.com>]

Hello guys,

I'd like to test SMB Direct. But it's failed. I'm not sure if it works in upstream.
I setup samba server on one rdma machine with 5.5.0-rc1+ kernel. The smb.conf is:
[cifs]
path=/mnt/cifs
writeable=yes

Then I try to mount the share on another rdma machine with 5.5.0-rc1+ kernel.
   mount //$RDMA/cifs cifs -o user=root,password=$password,rdma

It's failed because of "CIFS VFS: smbd_create_id:614 rdma_resolve_addr() completed -113"
Does SMB Direct work fine in upstream?

Thanks.

$ cat /boot/config-5.5.0-rc1+ |grep SMB_DIRECT
CONFIG_CIFS_SMB_DIRECT=y
$ ibstat
