fixfault() in fault.c is the only user of duppage().
in 9front, i changed the return type of duppage to void.
fixfault() now looks like this:
...
if(lkp->image == &swapimage)
ref = lkp->ref + swapcount(lkp->daddr);
else
ref = lkp->ref;
if(ref == 1 && lkp->image){
/* save a copy of the original for the image cache */
duppage(lkp);
ref = lkp->ref;
}
unlock(lkp);
if(ref > 1){
new = newpage(0, &s, addr);
if(s == 0)
return -1;
*pg = new;
copypage(lkp, *pg);
putpage(lkp);
}
...
