This patch fixes a build error reported in the link. [0]
unix_connect.c: In function ‘unix_connect_test’:
unix_connect.c:115:55: error: expected identifier before ‘(’ token
#define offsetof(type, member) ((size_t)&((type *)0)->(member))
^
unix_connect.c:128:12: note: in expansion of macro ‘offsetof’
addrlen = offsetof(struct sockaddr_un, sun_path) + variant->len;
^~~~~~~~
We can fix this by removing () around member, but checkpatch will complain
about it, and the root cause of the build failure is that I followed the
warning and fixed this in the v2 -> v3 change of the blamed commit. [1]
CHECK: Macro argument 'member' may be better as '(member)' to avoid precedence issues
#33: FILE: tools/testing/selftests/net/af_unix/unix_connect.c:115:
+#define offsetof(type, member) ((size_t)&((type *)0)->member)
To avoid this warning, let's use offsetof() defined in stddef.h instead.

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.
