Title:
  ftrace synthetic_events selftests failure in 5.11

Status in linux package in Ubuntu:
  Fix Committed
Status in linux source package in Hirsute:
  Fix Committed

Bug description:
  [Impact]

  The synthetic_events ftrace test is failing in 5.11:

  01:58:54 DEBUG| [stdout] # [68] event trigger - test synthetic_events
  syntax parser errors      [FAIL]

  This happens because the synthetic_event parser/syntax has been
  reworked in 5.12 and the selftest has been also updated. However, in
  5.11 we got only the commit that updates the test without the
  corresponding rework in the kernel, therefore the test is failing.

  [Fix]

  Revert the commit that updates the ftrace synthetic_events selftest.

  [Test plan]

  Run the linux ftrace selftest to trigger the problem (e.g., make
  TARGETS=ftrace kselftests).

  [Where problems could occur]

  This fix reverts a test case, if the kernel receives the ftrace rework
  via stable updates in the future we may see failures with the same
  test.
