From f3fe65122da05e1cd4c9140340d96ea2f95d0c49 Mon Sep 17 00:00:00 2001 From: Con Kolivas Date: Fri, 6 Jan 2006 00:11:15 -0800 Subject: [PATCH] mm: add populated_zone() helper There are numerous places we check whether a zone is populated or not. Provide a helper function to check for populated zones and convert all checks for zone->present_pages.
