Date: Wed, 29 Mar 2017 10:46:21 +0900 From: Namhyung Kim <namhyung@...nel.org> To: Steven Rostedt <rostedt@...dmis.org> Cc: Ingo Molnar <mingo@...nel.org>, Masami Hiramatsu <mhiramat@...nel.org>, LKML <linux-kernel@...r.kernel.org>, kernel-team@....com Subject: [PATCH 0/4] ftrace: Add 'function-fork' trace option (v1) Hello, This patchset add 'function-fork' option to function tracer which makes pid filter to be inherited like 'event-fork' does. During the test, I found a bug of pid filter on an instance directory. The patch 1 fixes it and maybe it should go to the stable tree. The function-fork option is disabled by default as event-fork does, but we might consider changing the default since it seems to be more natural from an user's perspective IMHO. The code is also available at 'ftrace/function-fork-v1' branch on git://git.kernel.org/pub/scm/linux/kernel/git/namhyung/linux-perf.git Thanks, Namhyung Namhyung Kim (4): ftrace: Fix function pid filter on instances ftrace: Add 'function-fork' trace option selftests: ftrace: Add -l/--logdir option selftests: ftrace: Add a testcase for function PID filter kernel/trace/ftrace.c | 47 ++++++++++- kernel/trace/trace.c | 6 +- kernel/trace/trace.h | 8 +- tools/testing/selftests/ftrace/ftracetest | 5 ++ .../ftrace/test.d/ftrace/func-filter-pid.tc | 98 ++++++++++++++++++++++ 5 files changed, 158 insertions(+), 6 deletions(-) create mode 100644 tools/testing/selftests/ftrace/test.d/ftrace/func-filter-pid.tc -- 2.12.0
