This patch merges two repeating pieces of code in one, and they will live in setup_net() now. The only change is that assignment: init_net_initialized = true; becomes reordered with: list_add_tail_rcu(&net->list, &net_namespace_list); The order does not have visible effect, and it is a simple cleanup because of: init_net_initialized is used in !CONFIG_NET_NS case to order proc_net_ns_ops registration occuring at boot time: start_kernel()->proc_root_init()->proc_net_init(), with net_ns_init()->setup_net(&init_net, &init_user_ns) also occuring in boot time from the same init_task. When there are no another tasks to race with them, for the single task it does not matter, which order two sequential independent loads should be made. So we make them reordered.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
