Kindly apply the patch to v4.4.y and v4.14.y.Why not 4.9.y and 4.19.y? You can not just skip stable kernel trees, otherwise people upgrading will have a regression. Anyway, the reason I did not backport the patch to older kernels is that it does not apply at all. If you have already done the backport (and I am guessing you have as otherwise how would you have tested this), please provide it to us so that we can apply it to all trees.
Let me fix up and submit the backport, give me a few minutes. I'll check it applies to the other stable trees as well. -Mathias
