No, I asked to move the changelog section to be not a part of the
commit message and asked what happened to the tags, because you
dropped them.

_If_ I understood the patch flow correctly, and it means that one is
the fix to the other one, then yes, otherwise no, keep them split with
appropriate Fixes tag added.

What do you mean by "tag" in this context? Do you mean "Subject" or
title? Otherwise it's very confusing.
For the Rb tag by me, yes, please keep it. As for Linus' one I think
you should drop it and add a changelog entry to explain why, because
that tag is only for the "fix" part. Do not forget to Cc Linus.

It's mandatory according to the Submitting Patches documentation. Read
it for clarification on how to use and when the tags.

I believe this needs more entries. Since it's not part of the commit
message, you may use free wording to explain what exactly had happened
to the patches, with links, references, etc.
