    LinuxKPI: stub anon_inode_getfile
    
    Although drm-kmod contains better implementation which is able to
    allocate real entries on pseudofs, this feature has never been used.
    
    Starting from drm-kmod v5.6 old implementation began to leak entries
    on each drm device close(). Now just drop pseudofs support instead of
    fixing it in drm-kmod and provide stub in base.
