From a938c356d5b007fe6d28251c0ddbf6c11d0d92b5 Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Fri, 23 Jun 2006 02:04:46 -0700 Subject: [PATCH] swsusp: take lowmem reserves into account swsusp allocates memory from the normal zone, so it cannot use lowmem reserve pages from the lower zones. Therefore it should not count these pages as available to it. Signed-off-by: Rafael J.
