Subject: [ 05/27] tracing: Fix double free when function profile init failed
Date: Sun, 14 Apr 2013 19:43:04 -0700 [thread overview]
Message-ID: <20130415024231.756692584@linuxfoundation.org> (raw)
In-Reply-To: <20130415024231.351969241@linuxfoundation.org>
3.8-stable review patch. If anyone has any objections, please let me know.
------------------
From: Namhyung Kim <namhyung.kim@lge.com>
commit 83e03b3fe4daffdebbb42151d5410d730ae50bd1 upstream.
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.
