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,
