Hi everyone, I’m looking at the code of domain_kill() to understand how a dying domain releases its resources. If I’m understanding correctly, physical memory is released by gradually releasing the page tables and updating the page_info associated to each entry to decrement reference counters until the page is finally scrubbed and released as the counters reach 0. Is that correct? If so, why is memory released that way and not by simply walking d->page_list and releasing pages as they appear in the list (assuming it’s not a shared page still used by another domain)?
