selftests/filesystems: add MOVE_MOUNT_BENEATH rootfs tests
Add tests for mounting beneath the rootfs using MOVE_MOUNT_BENEATH:
- beneath_rootfs_success: mount beneath /, fchdir, chroot, umount2
MNT_DETACH -- verify root changed
- beneath_rootfs_old_root_stacked: after mount-beneath, verify old root
parent is clone via statmount
- beneath_rootfs_in_chroot_fail: chroot into subdir of same mount,
mount-beneath fails (dentry != mnt_root)
- beneath_rootfs_in_chroot_success: chroot into separate tmpfs mount,
mount-beneath succeeds
- beneath_rootfs_locked_transfer: in user+mount ns: mount-beneath
rootfs succeeds, MNT_LOCKED transfers, old root unmountable
- beneath_rootfs_locked_containment: in user+mount ns: after full
root-switch workflow, new root is MNT_LOCKED (containment preserved)
- beneath_non_rootfs_locked_transfer: mounts created before
unshare(CLONE_NEWUSER | CLONE_NEWNS) become locked; mount-beneath
transfers MNT_LOCKED, displaced mount can be unmounted
- beneath_non_rootfs_locked_containment: same setup, verify new mount
is MNT_LOCKED (containment preserved)
