Pull ftrace updates from Steven Rostedt:

 - Fix regression of pid filtering of function graph tracer

   When the function graph tracer allowed multiple instances of graph
   tracing using subops, the filtering by pid broke.

   The ftrace_ops->private that was used for pid filtering wasn't
   updated on creation.

   The wrong function entry callback was used when pid filtering was
   enabled when the function graph tracer started, which meant that
   the pid filtering wasn't happening.

 - Remove no longer needed ftrace_trace_task()

   With PID filtering working via ftrace_pids_enabled() and
   fgraph_pid_func(), the coarse-grained ftrace_trace_task()
   check in graph_entry() is obsolete.

   It was only a fallback for uninitialized op->private (now fixed),
   and its removal ensures consistent PID filtering with standard
   function tracing.
