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