[ Upstream commit d8b26071e65e80a348602b939e333242f989221b ] Most of the fields in 'struct knfsd_fh' are 2 levels deep (a union and a struct) and are accessed using macros like: #define fh_FOO fh_base.fh_new.fb_FOO This patch makes the union and struct anonymous, so that "fh_FOO" can be a name directly within 'struct knfsd_fh' and the #defines aren't needed. The file handle as a whole is sometimes accessed as "fh_base" or "fh_base.fh_pad", neither of which are particularly helpful names. As the struct holding the filehandle is now anonymous, we cannot use the name of that, so we union it with 'fh_raw' and use that where the raw filehandle is needed. fh_raw also ensure the structure is large enough for the largest possible filehandle. fh_raw is a 'char' array, removing any need to cast it for memcpy etc. SVCFH_fmt() is simplified using the "%ph" printk format. This changes the appearance of filehandles in dprintk() debugging, making them a little more precise.

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.
