From 2e1483c995bbd0fa6cbd055ad76088a520799ba4 Mon Sep 17 00:00:00 2001 From: Catalin Marinas Date: Thu, 11 Jun 2009 13:24:13 +0100 Subject: kmemleak: Remove some of the kmemleak false positives There are allocations for which the main pointer cannot be found but they are not memory leaks. This patch fixes some of them. For more information on false positives, see Documentation/kmemleak.txt.
