Pull Kselftest fixes from Mickaël Salaün:
 "Fix Kselftest's vfork() side effects.

  As reported by Kernel Test Robot and Sean Christopherson, some
  tests fail since v6.9-rc1 . This is due to the use of vfork() which
  introduced some side effects. Similarly, while making it more generic,
  a previous commit made some Landlock file system tests flaky, and
  subject to the host's file system mount configuration.

  This fixes all these side effects by replacing vfork() with clone3()
  and CLONE_VFORK, which is cleaner (no arbitrary shared memory) and
  makes the Kselftest framework more robust"
