From 2fc1dfbe17e7705c55b7a99da995fa565e26f151 Mon Sep 17 00:00:00 2001 From: Frederic Weisbecker Date: Mon, 16 Mar 2009 01:45:03 +0100 Subject: [PATCH] tracing/core: fix early free of cpumasks Impact: fix crashes when tracing cpumasks While ring-buffer allocation, the cpumasks are allocated too, including the tracing cpumask and the per-cpu file mask handler. But these cpumasks are freed accidentally just after. Fix it.
