Title:
  test.d--ftrace--func_event_triggers.tc from ubuntu_kselftests_ftrace
  is flaky on s390x LPAR

Status in ubuntu-kernel-tests:
  New

Bug description:
  This issue was only spotted with Eoan (5.3.0-43.36) LPAR instances
  s2lp4

  # [20] ftrace - test for function event triggers        [FAIL]

  Passed with s390x zVM and zKVM

  However, it will pass if you run it directly:
  $ sudo ./ftracetest test.d/ftrace/func_event_triggers.tc
  === Ftrace unit tests ===
  [1] ftrace - test for function event triggers	[PASS]
  [2] (instance)  ftrace - test for function event triggers	[PASS]

  
  # of passed:  2
  # of failed:  0
  # of unresolved:  0
  # of untested:  0
  # of unsupported:  0
  # of xfailed:  0
  # of undefined(test bug):  0

  So it looks like a test case issue here.
