The length of the AF_UNIX socket address contains an offset to the member sun_path of struct sockaddr_un. Currently, the preceding member is just sun_family, and its type is sa_family_t and resolved to short. Therefore, the offset is represented by sizeof(short). However, it is not clear and fragile to changes in struct sockaddr_storage or sockaddr_un. This commit makes it clear and robust by rewriting sizeof() with offsetof().

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.
