hm. Aggregating dirty and unstable at inc/dec time is a bit kludgy. If later on we want to know just "dirty" then we're in trouble.
I can see the logic behind it though.
Perhaps one could have separate BDI_DIRTY and BDI_UNSTABLE and treat them separately at inc/dec time, but give them the same numerical value, so they in fact refer to the same counter. That's kludgy too. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
