From c7708649ccbdc21e85c95ca1a01b28342d939d39 Mon Sep 17 00:00:00 2001 From: Stefan Raspl <raspl@linux.vnet.ibm.com> Date: Tue, 12 Nov 2013 15:11:11 -0800 Subject: [PATCH] Documentation/trace/tracepoints.txt: 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.
