[PATCH 7/8] lsm: fix the security_namespace_init() kernel-doc

[sashiko-bot at kernel.org]

> The kernel-doc claims that the owning user namespace is available via
> ns->ops->owner(ns). But security_namespace_init() is called from
> __ns_common_init() before the namespace has been set up. Apart from
> network namespaces the owning user namespace isn't set at that point so
> ->owner() returns NULL. And for init_net with CONFIG_NET_NS=n ns->ops
> itself is NULL.
> 
> What a namespace_init hook can rely on is the namespace type and, now
> that it is allocated before the hook is called, the namespace id. So
> document that instead.
> 
> No functional changes.
> 
> Fixes: f675d2e95569 ("lsm: add LSM blob and hooks for namespaces")
> Cc: <stable at kernel.org> # mainline only
> Signed-off-by: Christian Brauner (Amutable) <brauner at kernel.org>
