From 60371d971a3d01afd102f0bbf2681f32ecc31d78 Mon Sep 17 00:00:00 2001 From: Hugh Dickins Date: Tue, 6 Jan 2009 14:39:40 -0800 Subject: mm: add add_to_swap stub If we add a failing stub for add_to_swap(), then we can remove the #ifdef CONFIG_SWAP from mm/vmscan.c. This was intended as a source cleanup, but looking more closely, it turns out that the !CONFIG_SWAP case was going to keep_locked for an anonymous page, whereas now it goes to the more suitable activate_locked, like the CONFIG_SWAP nr_swap_pages 0 case.
