Hi, this patchset consists of a fixup by an error that was reported by intel robot, where it seems to be that by the time page_owner gets initialized, stackdepot has already depleted its allocation space and returns 0-handles, turning that into null stack_records when trying to retrieve the stack_record. I was not able to reproduce that from the config because it booted fine for me, but when setting e.g: dummy_handle to 0 artificially, I could see the same error that was reported. The second patch is a cleanup that can also lead to a compilation warning.
