When a page is used for virtual memory, it is often necessary to obtain
a handler to the corresponding vm_struct, which refers to the virtually

The struct page has a "mapping" field, which can be re-used, to store a
pointer to the parent area.
This will avoid more expensive searches, later on.

provided last revision?)
Thanks,
Jay
