tracing: Rename struct ftrace_subsystem_dir to trace_subsystem_dir
The name "ftrace" really refers to the function hook infrastructure. It is not about the trace_events. The structure ftrace_subsystem_dir holds the information about trace event subsystems. It should not be named ftrace, rename it to trace_subsystem_dir. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
