Merge patch series "ns: header cleanups and initial namespace reference count improvements"
Christian Brauner <brauner@kernel.org> says:

Cleanup the namespace headers by splitting them into types and helpers.
Better separate common namepace types and functions from namespace tree
types and functions.

Fix the reference counts of initial namespaces so we don't do any
pointless cacheline ping-pong for them when we know they can never go
away. Add a bunch of asserts for both the passive and active reference
counts to catch any changes that would break it.

* patches from https://patch.msgid.link/20251110-work-namespace-nstree-fixes-v1-0-e8a9264e0fb9@kernel.org:

  ns: add asserts for initial namespace reference counts

  ipc: enable is_ns_init_id() assertions
  fs: use boolean to indicate anonymous mount namespace
  ns: rename is_initial_namespace()
  ns: make is_initial_namespace() argument const
  nstree: use guards for ns_tree_lock

  nstree: move nstree types into separate header
  nstree: decouple from ns_common header

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
