However, there's no need to repost patches *only* to add the tags. The upstream maintainer will do that for acks received on the version they apply. https://elixir.bootlin.com/linux/v5.17/source/Documentation/process/submitting-patches.rst#L540 If a tag was not added on purpose, please state why and what changed.
