Milk-V Jupiter Linux kernel
addf9b90de
rtnetlink is littered with READ_ONCE() because we can have read accesses while another cpu can write to the structure we're reading by (un)registering doit or dumpit handlers. This patch changes this so that (un)registering cpu allocates a new structure and then publishes it via rcu_assign_pointer, i.e. once another cpu can see such pointer no modifications will occur anymore. based on initial patch from Peter Zijlstra.

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.
