Merge patch series "ns: tweak ns common handling"
Christian Brauner <brauner@kernel.org> says:
This contains three minor tweaks for namespace handling:
* Make struct ns_tree private. There's no need for anything to access
that directly.
* Drop a debug assert that would trigger in conditions that are benign.
* Move the type of the namespace out of struct proc_ns_operations and
into struct ns_common. This eliminates a pointer dereference and also
allows assertions to work when the namespace type is disabled and the
operations field set to NULL.
* patches from https://lore.kernel.org/20250924-work-namespaces-fixes-v1-0-8fb682c8678e@kernel.org:
ns: drop assert
ns: move ns type into struct ns_common
nstree: make struct ns_tree private
