Message-ID: <20231013190350.579407-3-audra@redhat.com>
Date: Fri, 13 Oct 2023 15:03:46 -0400

Subject: [PATCH 2/5] tools/mm: Remove references to free_ts from page_owner_sort
With the removal of free timestamps from page_owner output, we no longer
need to handle this case or the "unreleased" case. Remove all references
to both cases.
