From 2425bcb9240f8c97d793cb31c8e8d8d0a843fa29 Mon Sep 17 00:00:00 2001 From: "Steven Rostedt (Red Hat)" Date: Tue, 5 May 2015 11:45:27 -0400 Subject: tracing: Rename ftrace_event_{call,class} to trace_event_{call,class} The name "ftrace" really refers to the function hook infrastructure. It is not about the trace_events. The structures ftrace_event_call and ftrace_event_class have nothing to do with the function hooks, and are really trace_event structures. Rename ftrace_event_* to trace_event_*.
