    Hi
I'm currently trying to reduce the dump time, and then I try to dump only
pages that are currently use by the system. In page structure I found a flag,
I was thinking a good one for this purpose:
atomic_t count;                 /* Usage count, see below. */

But after taking only pages where count != 0, something was broken, I was
not able to look at proc structure, and several things.....
If a do a "full" dump I'm still able to look at what I need, so this page.count
is not accurate for this purpose. So does't exist a good way to know if a page
is in use or not ?

    thanks.
