Pull ftrace testcase update from Steven Rostedt:
 "While testing my development branch, without the fix for the pid use
  after free bug, the selftest that Namhyung added triggers it. I
  figured it would be good to add the test for the bug after the fix,
  such that it does not exist without the fix.

  I added another patch that lets the test only test part of the pid
  filtering, and ignores the function-fork (filtering on children as
  well) if the function-fork feature does not exist. This feature is
  added by Namhyung just before he added this test. But since the test
  tests both with and without the feature, it would be good to let it
  not fail if the feature does not exist"
