Title:
  user_copy in user from ubuntu_kernel_selftests failed on KVM kernel

Status in ubuntu-kernel-tests:
  Fix Released
Status in linux-kvm package in Ubuntu:
  Invalid
Status in linux-kvm source package in Xenial:
  Fix Released
Status in linux-kvm source package in Bionic:
  Fix Committed
Status in linux-kvm source package in Cosmic:
  Fix Released

Bug description:
  == Justification ==
  This user_copy test has failed while attempting to insert the test_user_copy module, but this module does not exist in the Bionic KVM kernel as the CONFIG_TEST_USER_COPY was not enabled.

  # modprobe test_user_copy
  modprobe: FATAL: Module test_user_copy not found in directory /lib/modules/4.15.0-1028-kvm

  == Fix ==
  d7d5311 (selftests: user: return Kselftest Skip code for skipped tests)
  3c07aae (selftests: kselftest: change KSFT_SKIP=4 instead of KSFT_PASS)
  c31d02d (selftests: kselftest: Remove outdated comment)

  This fix will make the test return a skipped retun code if the
  test_user_copy module does not exist.

  This patch set can be cherry-picked into Bionic, and we already have
  it in Cosmic / Disco.

  For Xenial, it already got d7d5311 and does not need the other two.

  == Test ==
  With this patch, the test will return "skipped" as expected:
      $ sudo ./test_user_copy.sh
      user: module test_user_copy is not found [SKIP]
      $ echo $?
      4

  Note that the test framework will need another fix to treat the SKIP
  return code properly. (bug 1812352)

  == Regression potential ==
  None,
  this patch just change the code for the testing tool.

  This test_user_copy module will need the CONFIG_TEST_USER_COPY to be enabled
