From 89c837351db0b9b52fd572ec8b0445a42e59b75c Mon Sep 17 00:00:00 2001 From: Steven Rostedt Date: Wed, 15 May 2013 20:46:23 +0100 Subject: kmemleak: No need for scanning specific module sections As kmemleak now scans all module sections that are allocated, writable and non executable, there's no need to scan individual sections that might reference data.
