before jumping to action can we also please briefly consider the Linux 
kernel mount case with SMB3 Unix Extensions and mount over SMB?

The proposed approach makes sense for Windows clients, maybe be should 
incorporate exposing the raw namespace when UNIX extensions are 
negotiated. In the end this is likely going to be a made via a later MR 
in the future, but I'd like to see both cases considered now that we're 
making changes.
