I think adding a function like this is more simple way.
(call this istead of nr_free_pages().)
==
int nr_available_memory()
{
unsigned long sum = 0;
for_each_zone(zone) {
if (zone->free_pages > zone->pages_high)
sum += zone->free_pages - zone->pages_high;
}
return sum;
}
==
BTW, vm_enough_memory() doesn't eat cpuset information ?
