From 9e730237c2cb479649207da1be2114c28d2fcf51 Mon Sep 17 00:00:00 2001 From: Vegard Nossum Date: Sun, 22 Feb 2009 11:28:25 +0100 Subject: kmemcheck: don't track page tables As these are allocated using the page allocator, we need to pass __GFP_NOTRACK before we add page allocator support to kmemcheck.
