Subject: [PATCH 1/7] tracing: instance_rmdir() leaks ftrace_event_file->filter
Date: Fri, 11 Jul 2014 21:06:38 +0200	[thread overview]
Message-ID: <20140711190638.GA19517@redhat.com> (raw)
In-Reply-To: <20140711190622.GA19499@redhat.com>

instance_rmdir() path destroys the event files but forgets to free
file->filter. Change remove_event_file_dir() to free_event_filter().
