uevent_net_init() and uevent_net_exit() create and destroy netlink socket, and these actions serialized in netlink code. Parallel execution with other pernet_operations makes the socket disappear earlier from uevent_sock_list on ->exit. As userspace can't be interested in broadcast messages of dying net, and, as I see, no one in kernel listen them, we may safely make uevent_net_ops async.

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.
