A Samba bug for Linux clients. Sending 1mb minimum for Windows
clients causes them to use larger internal buffers and do
larger reads. So making this value 1mb is good for us when
serving Windows clients.

The "blocks used on disk" logic in smbd is one function
called from all the (several :-) different info levels
that return this value. I made this mistake of calling
it for the UNIX info level return also, instead of returning
the real value for UNIX clients (who can handle the truth
rather better than Windows :-).

I'll fix it for the next Samba release. Happy *now* ? :-).

Jeremy.
