The FILE_WRITE_THROUGH CreateOption basically means using
the O_SYNC mode on the open().  I agree with Chris that the
question doesn't really make sense since FILE_WRITE_THROUGH
is up to the server to enforce (or not).  You can enforce
equivalent FILE_WRITE_THROUGH semantics in smbd regardless of
whether or not the client requests it.
