Subject: [RFC PATCH v2 0/4] ftrace: Add a ftrace test collection

Hi,

Here is the collection of testcases for ftrace version 2.
In this version, I just updated the test framework according
to some discussions on kernel summit testing unconference.

The major updates are:
 - Using dash (busybox shell) instead of bash, because it
   allows us to test on the minimal environments running on 
   cross-arch emulators.
 - Support XFAIL/XPASS/UNSUPPORTED results for testcase.
   Some of ftrace features depend on kconfig and some of
   them do not work by environmental reason.
 - Support partial testing under given directory.

ftracetest is a small dash script for testing ftrace features.
It will be required to add a unit test for each new feature
after this is merged, because of preventing feature regressions.

This version still be out of the selftest. However, at the kernel
summit, I talked with Shuah about that. And since the kselftest
will be the standard kernel unit test framework, I agreed to
move this under the selftest. But I also would like to ask Steven
and Namhyung to agree with it before moving.

Actually, we've already has similar shell-script base testcase
under kselftest, see tools/testing/selftests/sysctl/Makefile.
I think we can mimic it for ftracetest :)

Thank you,
