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. thanks, greg k-h
