Message-Id: <1364820385-32027-1-git-send-email-namhyung@kernel.org> Date: Mon, 1 Apr 2013 21:46:23 +0900 From: Namhyung Kim <namhyung@...nel.org> To: Steven Rostedt <rostedt@...dmis.org>, Frederic Weisbecker <fweisbec@...il.com> Cc: LKML <linux-kernel@...r.kernel.org>, Namhyung Kim <namhyung.kim@....com> Subject: [PATCH 1/3] tracing: Fix double free when function profile init failed From: Namhyung Kim <namhyung.kim@....com> On the failure path, stat->start and stat->pages will refer same page. So it'll attempt to free the same page again and get kernel panic.
