[PATCH 0/2] trace-cmd list: Include ftrace in event listings

[Steven Rostedt <rostedt@goodmis.org>]

From: "Steven Rostedt (VMware)" <rostedt@goodmis.org>

I'm constantly needing to look at the event formats of ftrace events
(like the function event or print event), but trace-cmd list does not
include them, as they can not be enabled by trace-cmd record/start.

By default, trace-cmd list -e, wont show ftrace events, but if a regex
is added to the search: trace-cmd list -e print, then it will now list
those events in ftrace. This is useful for:

 # trace-cmd list -e ftrace:function -F
system: ftrace
name: function
ID: 1
format:
        field:unsigned short common_type;       offset:0;       size:2; signed:0;
        field:unsigned char common_flags;       offset:2;       size:1; signed:0;
        field:unsigned char common_preempt_count;       offset:3;       size:1; signed:0;
        field:int common_pid;   offset:4;       size:4; signed:1;

        field:unsigned long ip; offset:8;       size:8; signed:0;
        field:unsigned long parent_ip;  offset:16;      size:8; signed:0;

  trace-cmd list: Use tracefs to help find events for -e
  trace-cmd list: Add ftrace events to listing of events
