Looks nice. The lack of testing results is conspicuous ;) It only really solves the problem in the case where size-of-inactive-list < size-of-working-set < size-of-total-memory yes? In fact less than that, because the active list presumably doesn't get shrunk to zero (how far *can* it go?). I wonder how many workloads fit into those constraints in the real world. -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
