Message-Id: <1464034111-25340-1-git-send-email-computersforpeace@gmail.com> Date: Mon, 23 May 2016 13:08:31 -0700 From: Brian Norris <computersforpeace@...il.com> To: Steven Rostedt <rostedt@...dmis.org> Cc: <linux-kernel@...r.kernel.org>, <linux-doc@...r.kernel.org>, Brian Norris <computersforpeace@...il.com>, Jonathan Corbet <corbet@....net>, Li Zefan <lizf@...fujitsu.com> Subject: [PATCH] doc: clarify that trace_events= takes a comma-separated list It took me browsing through the source code to determine that I was, indeed, using the wrong delimiter in my command lines.
