Patches look nice, but unfortunately only -mm stuff and will need to be rebased once 2.6.23 opens anyway.
Where are we on the ondemand read-ahead merging? -mm has continually had different read-ahead code than mainline now for seemingly years, seems a bit pointless to me. Either we get the stuff merged, or toss it out. Nothing needs to simmer that long.
I suspect we wont see any real potential regressions before it hits mainline anyway.
