Technically, the issue was present before, but I doubt adding pre-v3.18
Fixes tags would make any difference for stable...

There is a better way to constrain backporting, that is Cc: 
stable@vger.kernel.org # 3.12+

The reason I mention it is that Fixes tags could be seen as a way to 
identify commits that introduce bugs, e.g. for the purposes of training 
AIs, or attributing blame, or measuring quality etc. I think it would be 
unfair to point the finger at Peter's commit.
