Well maybe. The `lru' arg to __lru_cache_add is still there and is rather misleading (I find it maddening ;)). AIUI, it's just there as the means by which the __lru_cache_add() caller tells the LRU manager that the caller wishes this page to start life on the active LRU, yes? It doesn't _really_ specify an LRU list at all. In which case I think it would be a heck of a lot clearer if the callers were to do SetPageActve(page); __lru_cache_add(page); no? (Or __lru_cache_add_active(page) and __lru_cache_add_inactive(page) if one prefers). Ditto lru_cache_add_lru() and probably other things. Let's have one way of communicating activeness, not two. -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
