Message-ID: <20101016131505.GW14064@sgi.com> MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline User-Agent: Mutt/1.5.20 (2009-06-14) Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org Just started looking into using ftrace to identify a difficult to diagnose userland set of processes when I noticed that the .../trace/per_cpu directory only contains entries for cpus 0-999. I have not looked at what else may not work. For the cpus that are listed, I am able to grep trace buffer information so it is mostly working. I will be away from email for most of today, but may get back to this tonight. If there are any suggestions, I will happily give them a try. Thanks, Robin
