Well, stable does not appear to have its usual meaning in the 2.4 series,
this code however, appeared in 2.4.4 back in April, so has been there for
a while now. I am not sure what happened with dd though. Are you sure you
are using the same user space - it may be that O_LARGEFILE has gone
missing on you somehow.
