Title:
  landlock04 from ubuntu_ltp_syscalls failed on Jammy (TBROK:
  landlock_add_rule)

Status in ubuntu-kernel-tests:
  New

Bug description:
  This is a new test case added on Aug. 8
  https://github.com/linux-test-project/ltp/commit/0e19ce15690055231fe4954e8b3711a3a47c937a

  And we got our fork updated recently in order to cover Oracular.
  So this is not a regression.

  Test failed with:
    TBROK: landlock_add_rule(8, 1, 0xfffd3c6ffff4, 0): EINVAL (22)

  On all 7 testable filesystems in the end of the test.
