The need here would be that people sometimes need to specify a smaller
rsize, because of broken ethernet cards in client or server, or
some routing problem. When doing this, you also must set the readdir size
to a smaller value, otherwise things will still break.

Also, the behaviour as described above is the same as it used to be for v2
(where the rsize was used for readdir requests) and it doesn't change the
ability for people to change the readdirsize seperately.

To put it another way: what would be a situation in which you would _not_
want this behaviour?
