When initialising the root netns, we call preinit_net() under pernet_ops_rwsem. However, the operations in preinit_net() do not require pernet_ops_rwsem. Also, we don't hold it for preinit_net() when initialising non-root netns. To be consistent, let's call preinit_net() without pernet_ops_rwsem in net_ns_init().

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.
