If you send it to stable with a tag like,

  CC: <stable@vger.kernel.org> # 5.15.x

or whatever kernel you need this has worked from me. This has worked for
me if I understood the above question correctly. The relevant docs are in
Documentation/process/stable-kernel-rules.rst. The following bit seems to
explain it.

 * For patches that may have kernel version prerequisites specify them using
   the following format in the sign-off area:

   .. code-block:: none

     Cc: <stable@vger.kernel.org> # 3.3.x

   The tag has the meaning of:

   .. code-block:: none

     git cherry-pick <this commit>

   For each "-stable" tree starting with the specified version.

   Note, such tagging is unnecessary if the stable team can derive the
   appropriate versions from Fixes: tags.

 * To delay pick up of patches, use the following format:

   .. code-block:: none

     Cc: <stable@vger.kernel.org> # after 4 weeks in mainline

 * For any other requests, just add a note to the stable tag. This for example
   can be used to point out known problems:

   .. code-block:: none

     Cc: <stable@vger.kernel.org> # see patch description, needs adjustments for <= 6.3
