Presumably we could make this consistent either by counting SLRU
writes in both places, or by counting them in neither place. This
proposal would count them in both places. But why is that the right
thing to do?
I'm somewhat inclined to think that we should use "buffers" to mean
regular data buffers, and if SLRU buffers also need to be counted, we
ought to make that a separate counter. Or just leave it out
altogether.
This is arguable, though, for sure....
