Yes, for i915* it de facto restores the old behaviour.

But there is other code that also returns SHRINK_STOP. So i believe it´s better to
adapt shrink_slab_node() to handle SHRINK_STOP properly than to revert 81e49f.

I agree. They´ll probably have to apply some additional changes to
shrink_slab_node(). It really doesn´t look right to me, but they certainly
know better what the code is supposed to do ;-)
