commit d4a11d6a22cf73ac7441750e5e8113779348885e Author: Jason Andryuk <jandryuk@xxxxxxxxx> AuthorDate: Mon Oct 31 13:21:31 2022 +0100 Commit: Jan Beulich <jbeulich@xxxxxxxx> CommitDate: Mon Oct 31 13:21:31 2022 +0100 argo: Remove reachable ASSERT_UNREACHABLE I observed this ASSERT_UNREACHABLE in partner_rings_remove consistently trip. It was in OpenXT with the viptables patch applied. dom10 shuts down. dom7 is REJECTED sending to dom10. dom7 shuts down and this ASSERT trips for dom10. The argo_send_info has a domid, but there is no refcount taken on the domain. Therefore it's not appropriate to ASSERT that the domain can be looked up via domid. Replace with a debug message.
