From 7f1d2f8210195c8c309d424a77dbf06a6d2186f4 Mon Sep 17 00:00:00 2001 From: "Steven Rostedt (Red Hat)" Date: Tue, 5 May 2015 10:09:53 -0400 Subject: [PATCH] tracing: Rename ftrace_event_file to trace_event_file 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.
