From 008139d9146f9afee0e58df4b7422d0c9921f8ce Mon Sep 17 00:00:00 2001 From: Catalin Marinas <catalin.marinas@arm.com> Date: Thu, 27 Aug 2009 14:29:17 +0100 Subject: kmemleak: Do not report alloc_bootmem blocks as leaks This patch sets the min_count for alloc_bootmem objects to 0 so that they are never reported as leaks. This is because many of these blocks are only referred via the physical address which is not looked up by kmemleak.
