[RFC][PATCH 06/19] tracing: Rename ftrace_event_file to trace_event_file

From: Steven Rostedt
Date: Thu May 14 2015 - 11:20:01 EST

From: "Steven Rostedt (Red Hat)" <rostedt@xxxxxxxxxxx>

The name "ftrace" really refers to the function hook infrastructure. It
is not about the trace_events. The structure ftrace_event_file is really
about trace events and not "ftrace". Rename it to trace_event_file.

Signed-off-by: Steven Rostedt <rostedt@xxxxxxxxxxx>
