folio_is_secretmem() states that secretmem folios cannot be LRU folios: so we may only exit early if we find an LRU folio. Yet, we exit early if we find a folio that is not a secretmem folio.

Thanks, I split up this series. Because this patch goes mm-hotfixes-unstable -> mm-hotfixes-stable -> mainline whereas the other two go mm-unstable -> mm-stable -> mainline at a later time.

Makes sense. I'll resend a v2 later, because there are some major changes (the fix was wrong/incomplete, we have to remove the LRU test completely).
