Yeah, the "reclaimable" name is too generic. How about KReclaimable? The counter being a superset sounds good to me. We use this info for both load balancing and manual debugging. For load balancing code it's nice not having to worry about finding all the counters that hold reclaimable memory depending on kernel version; it's always simply user cache + user anon + kernel reclaimable. And for debugging, we can always add more specific subset counters later on if we need them. -- To unsubscribe from this list: send the line "unsubscribe linux-api" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
