In short, yes and no. Before you can get a coherent answer to your question, I will ask you "why".
I.E. What are you looking for from a "unified buffer cache" - mmap coherency? Because things are being worked on, however we just may not be doing it the way you are thinking. So let me be clear - UBC is a particular way of implementing things. What "things" are you looking for from UBC - because we may already be doing that without UBC. 2010/1/29 Bret S.
