Subject: [PATCH 0/4] tracing: Small updates on tracing/set_graph_notrace file

Hello,

This is an update of recent notrace filter change in the function graph
tracer.  It adds a new kernel boot parameter and also adds description of
the file to the tracing/README in debugfs.  Finally it changes message
when the (both of) notrace filter hash is empty.  They'll print below
message when there's no entry:

  # cat /sys/kernel/debug/tracing/set_graph_notrace
  #### no functions disabled ####


It's also available at 'ftrace/nograph-v3' branch in my tree

  git://git.kernel.org/pub/scm/linux/kernel/git/namhyung/linux-perf.git

Thanks,
Namhyung
