Merge tag 'landlock-6.5-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/mic/linux

Pull landlock updates from Mickaël Salaün:
 "Add support for Landlock to UML.

  To do this, this fixes the way hostfs manages inodes according to the
  underlying filesystem [1]. They are now properly handled as for other
  filesystems, which enables Landlock support (and probably other
  features).

  This also extends Landlock's tests with 6 pseudo filesystems,
  including hostfs"
