Hi,

Here is the collection of testcases for ftrace version 5.
This is just a small update.

  - Fix a TODO item, since this already integrated to kselftest.
  - Print the test name at the first line.
  - Add Shuah's acked-by. (Thanks!)

ftracetest is a shell(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 regressions.

Thank you,

---

ftracetest is a collection of testcase shell-scripts for ftrace.
To avoid regressions of ftrace, these testcases check correct
ftrace behaviors. If someone would like to add any features on
ftrace, the patch series should have at least one testcase for
checking the new behavior.

Changes in v5:
 - Fix a TODO item, since this already integrated to kselftest.
 - Print the test name at the first line.

Changes in v4:
 - Move this under selftests. :)
 - Add a copyright and note of GPLv2.
 - Fix documents acconding to Steven's comments.
 - Fix a small bug pointed by Namhyng.

Changes in v3:
 - Use "." instead of "source".
 - Don't use -e option for echo since dash doesn't support it.

Changes in v2:
 - Remove unneeded 'function' keyword.
 - Add abspath and find_testcases.
 - Make OPT_TEST_CASES a local var.
 - Ensure given testcase ended with .tc.
 - Accept a directory option which has multiple testcases.
 - Change [PASSED]/[FAILED] to [PASS]/[FAIL]
 - Change the basic shell to sh (dash).

+Linux Ftrace Testcases
+
+This is a collection of testcases for ftrace tracing feature in the Linux
+kernel. Since ftrace exports interfaces via the debugfs, we just need
+shell scripts for testing. Feel free to add new test cases.
+
+Running the ftrace testcases
+============================
+
+At first, you need to be the root user to run this script.
+To run all testcases:
+
+  $ sudo ./ftracetest
+
+To run specific testcases:
+
+  # ./ftracetest test.d/basic3.tc
+
+Or you can also run testcases under given directory:
+
+  # ./ftracetest test.d/kprobe/
+
+Contributing new testcases
+==========================
+
+Copy test.d/template to your testcase (whose filename must have *.tc
+extension) and rewrite the test description line.
+
+ * The working directory of the script is <debugfs>/tracing/.
+
+ * Take care with side effects as the tests are run with root privilege.
+
+ * The tests should not run for a long period of time (more than 1 min.)
+   These are to be unit tests.
+
+ * You can add a directory for your testcases under test.d/ if needed.
+
+ * The test cases should run on dash (busybox shell) for testing on
+   minimal cross-build environments.
+
+TODO
+====
+
+ * Fancy colored output :)

Place the version changes after the '---'. They are great for patch
series, but we prefer not to have them in the git logs. The "Link:" tag
should allow people to find the version history of patches if they are
interested. By placing the version updates after the '---', git will
ignore them when pulling them in.

Also, please have the Signed-off-by be the last tag, otherwise it
screws up my scripts ;-)

Ah, I see :)
For the next series, I'll do that.

Add ftrace basic testcases. This just checks ftrace debugfs
interface works as it is designed.

Changes in v2:
  - Change shell to sh instead of bash.

Add basic testcases for kprobe dynamic events.
This also shows that the ftracetest accepts sub-directory
for new testcases.

Changes in v2:
  - Change shell to sh instead of bash.

Add XFAIL and POSIX 1003.3 standard codes (UNRESOLVED/
UNTESTED/UNSUPPORTED) as result codes. These are used for the
results that test case is expected to fail or unsupported
feature (by config).

To return these result code, this introduces exit_unresolved,
exit_untested, exit_unsupported and exit_xfail functions,
which use real-time signals to notify the result code to
ftracetest.

This also set "errexit" option for the testcases, so that
the tests don't need to exit explicitly.

Changes in v4:
 - Remove XPASS and short-names.
 - Use real-time signals for result code.
 - Simplify test cases by using errexit option.
 - Add sample scripts for result code.

Changes in v3:
 - Add UNRESOLVED/UNTESTED codes.
 - Fix to handle undefined codes.
 - Add a document about return codes.
 - Fix to show failure logs.
 - Don't use -e option for echo since dash doesn't support it.

  * The test cases should run on dash (busybox shell) for testing on
    minimal cross-build environments.
 
+ * Note that the tests are run with "set -e" (errexit) option. If any
+   command fails, the test will be terminated immediately.
+
+ * The tests can return some result codes instead of pass or fail by

+
+Result code
+===========
+
+Ftracetest supports following result codes.
+
+ * PASS: The test succeeded as expected. The test which exits with 0 is
+         counted as passed test.
+
+ * FAIL: The test failed, but was expected to succeed. The test which exits
+         with !0 is counted as failed test.
+
+ * UNRESOLVED: The test produced unclear or intermidiate results.
+             for example, the test was interrupted
+                       or the test depends on a previous test, which failed.
+                       or the test was set up incorrectly
+             The test which is in above situation, must call exit_unresolved.
+
+ * UNTESTED: The test was not run, currently just a placeholder.
+             In this case, the test must call exit_untested.
+
+ * UNSUPPORTED: The test failed because of lack of feature.
+               In this case, the test must call exit_unsupported.
+
+ * XFAIL: The test failed, and was expected to fail.
+          To return XFAIL, call exit_xfail from the test.
+
+There are some sample test scripts for result code under samples/.
+You can also run samples as below:
