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 Cc: Naoya Horiguchi Namhyung Kim (4): tracing: Add ftrace_graph_notrace boot parameter tracing: Improve message of empty set_graph_notrace file tracing: Improve message of empty set_ftrace_notrace file tracing: Add description of set_graph_notrace to tracing/README Documentation/kernel-parameters.txt | 6 +++++ kernel/trace/ftrace.c | 46 ++++++++++++++++++++++++++++++----- kernel/trace/trace.c | 1 + 3 files changed, 47 insertions(+), 6 deletions(-) -- 1.7.9.2
