That makes sense. I've updated the test to verify both the case where the elements are from the same list and where it's from a different list: https://lore.kernel.org/linux-kselftest/20220208040122.695258-2-davidgow@google.com/T/#u
(I've also updated patch 3 for list_entry_is_head() similarly, which was even worse before.)
