From 609a74045238c303bbe9396775eacf5bac1f51cc Mon Sep 17 00:00:00 2001 From: "Steven Rostedt (Red Hat)" Date: Wed, 13 May 2015 13:44:36 -0400 Subject: tracing: Rename FTRACE_MAX_EVENT to TRACE_EVENT_TYPE_MAX The name "ftrace" really refers to the function hook infrastructure. It is not about the trace_events. Rename the max trace_event type size to something more descriptive and appropriate.
