From 118c71bcacce82a4317c9bd99c6a15af14020aee Mon Sep 17 00:00:00 2001 From: Yasunori Goto Date: Tue, 13 Dec 2005 17:03:37 -0800 Subject: [PATCH] [PATCH] Fix calculation of grow_pgdat_span() in mm/memory_hotplug.c The calculation for node_spanned_pages at grow_pgdat_span() is clearly wrong. This is patch for it. (Please see grow_zone_span() to compare. It is correct.)
