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" Link: https://lore.kernel.org/oe-lkp/202403291015.1fcfa957-oliver.sang@intel.com Link: https://lore.kernel.org/r/ZjPelW6-AbtYvslu@google.com Link: https://lore.kernel.org/r/20240511171445.904356-1-mic@digikod.net * tag 'kselftest-fix-vfork-2024-05-12' of git://git.kernel.org/pub/scm/linux/kernel/git/mic/linux: selftests/harness: Handle TEST_F()'s explicit exit codes selftests/harness: Fix vfork() side effects selftests/harness: Share _metadata between forked processes selftests/pidfd: Fix wrong expectation selftests/harness: Constify fixture variants selftests/landlock: Do not allocate memory in fixture data selftests/harness: Fix interleaved scheduling leading to race conditions selftests/harness: Fix fixture teardown selftests/landlock: Fix FS tests when run on a private mount point selftests/pidfd: Fix config for pidfd_setns_test
