[ Upstream commit 942238f9735a4a4ebf8274b218d9a910158941d1 ] sk->sk_state is changed under unix_state_lock(), but it's read locklessly in many places. This patch adds WRITE_ONCE() on the writer side. We will add READ_ONCE() to the lockless readers in the following patches.

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 Restructured Text 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.
