No, the superfluous lstat check is if you have local directories or files in
a dfs root share.

Looking at the code, I don't really do an explicit lp_host_mdfs() check. I
check to see if the DFS_PATHNAME flag is set in the smb header. This implies
that DFS was successfully negotiated which can happen only if "host msdfs =
yes".

While we're on the subject, I've also been thinking for a while now, about
having dfs links in subdirectories of the dfs root. Currently, you can only
have dfs links in the dfs root directory itself, although you can have
multiple dfs roots on one machine.
