From: Rajesh Ghanekar Content-Type: text/plain; charset=ISO-8859-1 Sender: owner-linux-mm@kvack.org List-ID: To: linux-mm@kvack.org Hi, I am confused with what protects page->lru? Is it both zone->lru_lock or zone->lock? I can see it being protected either by lru_lock or lock. Are their any rules where to use lru_lock and where to use lock? I did google but couldn't find anything. Sorry if its already discusses elsewhere, but I couldn't locate any. - Rajesh -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
