I already pointed out to Richard privately, the
changes in master for SMB2 unix extensions should
allow him to do what is needed here.

All SMB1/2/3 create requests set UCF_PREP_CREATEFILE
in the lookup stage and pass to unix_convert(), which
resolves into a struct smb_filename. That now has
the 'flags' field that can be mapped into a vendor-specific
flag that should be able to do what he needs - even
for DFS lookups.
