Currently SMB2 and SMB3 mounts do not query the device information at mount time from the server as is done for cifs. These can be useful for debugging. This is a minor patch, that extends the previous one (which added ability to query file system attributes at mount time - this returns the device characteristics - also via in /proc/fs/cifs/DebugData) Signed-off-by: Steve French <smfrench@gmail.com>
