Yes. I read the docs before I wrote.

I didn't want the commit to be cherry-picked as it's already there (under 
different commit IDs) in some stable trees.

The prerequisite commit is df66834a in mainline (merged in 3.10). It is 
known as f64747c9 in 3.9.y and 8cfd67a3 in 3.4.y.

I only checked the trees in linux-stable.git which is not exhaustive but 
there are some stable trees that don't have it at all.

Perhaps it would be best to request that the new patch only gets applied 
where the prerequisite patch was already in mainline, i.e. >= 3.10.
