Future patches will call these tests within a userns. So, let's skip

On newer kernels you can always do:
mknodat(open_tree_fd, CHRDEV1, S_IFCHR | 0644, makedev(0, 0)))
but you'd still need the t_inside_userns then anyway so sure,
Actually, no, changing the makedev to that does the trick and it works
inside a userns (at least in kernels where tmpfs supports idmap mounts).
So I will just do that instead, thanks!
