The SMB1 processing takes place above the VFS
layer. It would be more work to do that refactoring
than it would to keep the existing SMB1 mapping
working.

The only way to simplify the fileserver is to
remove the SMB1 code and leave us as SMB2-only.

Use old-Samba mounted on cifsfs (via a vm maybe)
exporting SMB1 to an SMB2 server seems the only
sane solution for old devices to me.
