Subject: [PATCH RFC] mm: reverse lru scanning order
Date: Wed, 27 Jul 2011 15:10:02 +0400 [thread overview]
Message-ID: <20110727111002.9985.94938.stgit@localhost6> (raw)
LRU scanning order was accidentially changed in commit v2.6.27-5584-gb69408e:
"vmscan: Use an indexed array for LRU variables".
Before that commit reclaimer always scan active lists first.
This patch just reverse it back.
This is just notice and question: "Does it affect something?"
