Subject: [PATCH] documentation: Add links to TRACE_EVENT documentation
Date: Mon, 23 Sep 2013 09:36:23 +0200 [thread overview]
Message-ID: <523FEF77.4020709@linux.vnet.ibm.com> (raw)
documentation: Add links to TRACE_EVENT documentation
Existing tracepoint documentation doesn't mention the popular
TRACE_EVENT
macro. Since an excellent series of articles on proper usage already
exists, respective links are added to the existing documentation.

If the tracepoint has to be used in kernel modules, an

used to export the defined tracepoints.
