I see that linux-4.1.y is still at 5880876e9469 which has the serious
bug introduced by the backport c5ad33184354 "mm/swap.c: flush lru
pvecs on compound page arrival".

The analogous problem is also still affecting at least linux-3.18.y.

Is there some problem with reverting this patch in the stable
branches ?

Thanks,
Ian.
