pmap->pm_stats.resident_count

[Rao, Nikhil]

vm_daemon() looks at pmap->pm_stats.resident_count in the pmap structure
using vmspace_resident_count() which calls pmap_resident_count(),
pm_stats.resident_count is also incremented for device memory either if
the device memory has been mapped using pmap_object_init_pt or using
pmap_enter.
Since these pages do not belong to memory that is managed by the kernel,
they should not really be accounted in the if check below in
vm_pageout.c ?

   				    if (limit >= 0 && size >= limit) {
1593                                 vm_pageout_map_deactivate_pages(
1594                                     &p->p_vmspace->vm_map, limit);
1595                         }

Is my understanding correct ? What do the members of this list think ?

Thanks,
Nikhil
