From 160cb5a97daef0cb894685d84c9d4700bb7cccb4 Mon Sep 17 00:00:00 2001 From: Namhyung Kim Date: Thu, 19 Jan 2012 23:23:10 +0100 Subject: PM / Hibernate: Correct additional pages number calculation The struct bm_block is allocated by chain_alloc(), so it'd better counting it in LINKED_PAGE_DATA_SIZE.
