Subject: [PATCH v2] doc: clarify that trace_events= takes a comma-separated list
Date: Mon, 23 May 2016 13:37:58 -0700	[thread overview]
Message-ID: <1464035878-29685-1-git-send-email-computersforpeace@gmail.com> (raw)
In-Reply-To: <1464034111-25340-1-git-send-email-computersforpeace@gmail.com>

It took me browsing through the source code to determine that I was,
indeed, using the wrong delimiter in my command lines. So I might as
well document it for the next person.

v2: remove language about /sys/kernel/debug/tracing/set_event, to avoid
    implying it also takes a comma separated list
