[ Upstream commit832738e4b3] Compilers may optimize the layout of C structures, so we should not rely on sizeof struct and memcpy to encode and decode XDR structures. The byte order of the fields should also be taken into account. This patch adds the correct functions to handle the deviceid4 structure and removes the pad field, which is currently not used by NFSD, from the runtime state. The server's byte order is preserved because the deviceid4 blob on the wire is only used as a cookie by the client.

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 reStructuredText 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.
