How to traverse all resident pages in kernel?

[Yue Chen]

Hi all,

For research purposes, I am trying to get all the virtual memory starting
address of every page in kernel.

First I tried to traverse vm_map_entry and its sub-entries to get the
address range. However, not all the pages are present between the ``start''
and the ``end''. (struct vm_map_entry *node, node->start, node->end).

Then I tried to get the virtual address of each page by vm_object and
vm_page, but it seems nothing describing the page virtual address in these
structures.

Is there any way to get all the resident pages' virtual addresses in kernel?

Best regards,
Yue
