From 17bb9e0d906b625f86e9d31740bb1c35bc0f63d7 Mon Sep 17 00:00:00 2001 From: Catalin Marinas Date: Mon, 29 Jun 2009 17:13:56 +0100 Subject: kmemleak: Do not report new leaked objects if the scanning was stopped If the scanning was stopped with a signal, it is possible that some objects are left with a white colour (potential leaks) and reported. Add a check to avoid reporting such objects.
