Commit 0808e80cb760de2733c0527d2090ed2205a1eef8. It won't apply,
backporting is rather easy, though.
I thought this was a patch in the middle of a larger series, but
obviously I misremembered. It was the first patch of that series.
I'll send a series in case you don't object:
- revert of stable-4.9 944e0fc51a89c9827b98813d65dc083274777c7f
- backport of 0808e80cb760de2733c0527d2090ed2205a1eef8
- new backport of def9331a12977770cc6132d79f8e6565871e8e38
