Note that for a patch series, you do not have to list as prerequisites the
patches present in the series itself. For example, if you have the following
patch series::
patch1
patch2
where patch2 depends on patch1, you do not have to list patch1 as
prerequisite of patch2 if you have already marked patch1 for stable
inclusion.
In that case, I think, we should mark all 3 patches for stable inclusion.
