As far as I remember, rsize and wsize are negotiated between client
and
server. Those mount options just set an upper limit which is certainly
not what you want. I'm even wondering that those settings are accepted
at all! Normally, unsigned 16bit integer has a range from 0 to
65535. If
you ask me, that's an off-by-one error just waiting to happen...
This seems to suggest that 32768 is the largest figure that can be
specified for rsize,wsize:
