Can't delete this one, but can delete all the uts namespaces, obviously.
As with init_tgcred in kernel/cred.c.

It's initialized with a refcount which will keep it from ever getting
freed.

If we create it dynamically, then I don't think we can use it the way we
do in kernel/utsname_sysctl.c for instance.
