Title:
  ubuntu_kernel_selftests / ftrace:ftracetest do_softirq failure on
  Jammy realtime

Status in ubuntu-kernel-tests:
  Fix Released
Status in linux package in Ubuntu:
  Fix Released
Status in linux source package in Jammy:
  Fix Released

Bug description:
  [Impact]

  * ubuntu_kernel_selftests / ftrace:ftracetest fails on realtime
  kernel.

  * ftrace:ftracetest which reports: "echo: I/O error". This is caused
  by using "do_softirq" in test which does not exist on preempt RT
  kernel.

  [Fix]

  * Use other function.
  * Upstream commit 6fec1ab67f8d ("selftests/ftrace: Do not trace do_softirq because of PREEMPT_RT")

  [Test Plan]

  * Run the test on regular (base) and realtime kernel.

  [Where problems could occur]

  * Only ftracetest tests.

  [Other info]

  Failure is reported for step 32 in Jenkins job:
