From 0a5d649018b151cb9331c213a843ac4a3e7e44ab Mon Sep 17 00:00:00 2001 From: Jody McIntyre Date: Tue, 24 Mar 2009 16:00:28 -0400 Subject: tracing: Documentation / sample code fixes for tracepoints Fix the tracepoint documentation to refer to "tracepoint-sample" instead of "tracepoint-example" to match what actually exists; fix the directory, and clarify how to compile. Change every instance of "example" in the sample tracepoint code to "sample" for consistency.
