I guess that this is fine per stable document as it mention such example:
https://www.kernel.org/doc/html/latest/process/stable-kernel-rules.html
I have already in past sent patches with Fixes:hash1 and CC:stable/hash2
and were taken correctly.

I'm not sure what is the correct meaning of Fixes tag. I included it to
easily determinate in which commit was introduced member name "rsvd"
which should have been named "rootcap".
Submitting patches document is not fully clear for me as I understood it
that Fixes and CC:stable are two different things. E.g. it mention
"Attaching a Fixes: tag does not subvert ... the requirement to Cc:
stable@vger.kernel.org on all stable patch candidates." which I
understood that patch for backporting needs to have Cc:stable:
https://www.kernel.org/doc/html/latest/process/submitting-patches.html
But I will change it as needed. Just I did not know what is "the correct
way".
