I've just dropped them all as 72239f2795fa ("netfilter: nft_set_rbtree:
Drop spurious condition for overlap detection on insertion") didn't make
it into Linus's tree yet.

Yup, this confusion has caused for quite a few netfilter fixes to not
land in -stable. If it goes through Pablo's tree (and unless he intructs
otherwise), you should Cc stable.
