From 13466c8419c3ab3ccd5e905eef53ca49c6c201be Mon Sep 17 00:00:00 2001 From: Yasunori Goto Date: Fri, 1 Jun 2007 00:46:53 -0700 Subject: [PATCH] memory hotplug: fix unnecessary calling of init_currenty_empty_zone() zone->present_pages is updated in online_pages(). But, __add_zone() can be called twice or more before calling online_pages(). So, init_currenty_empty_zone() can be called unnecessary times. It is cause of memory leak of zone's wait_table.
