From e13861d822f8f443ca0c020ea8fc2dc01039cd63 Mon Sep 17 00:00:00 2001 From: Minchan Kim Date: Mon, 24 May 2010 14:31:59 -0700 Subject: mm: remove return value of putback_lru_pages() putback_lru_page() never can fail. So it doesn't matter count of "the number of pages put back". In addition, users of this functions don't use return value. Let's remove unnecessary code.
