Message-Id: <1380357239-30102-1-git-send-email-bob.liu@oracle.com>
Date: Sat, 28 Sep 2013 16:33:58 +0800
From: Bob Liu <lliubbo@...il.com>
To: akpm@...ux-foundation.org

Subject: [PATCH] mm: pagevec: cleanup: drop pvec->cold argument in all places
Nobody uses the pvec->cold argument of pagevec and it's also unreasonable for
pages in pagevec released as cold page, so drop the cold argument from pagevec.
