Zero-length arrays are deprecated and we are moving towards adopting C99 flexible-array members, instead. So, replace zero-length array declarations in a couple of structures and unions with the new DECLARE_FLEX_ARRAY() helper macro. This helper allows for a flexible-array member in a union and as only member in a structure. Also, this addresses multiple warnings reported when building with Clang-15 and -Wzero-length-array. Lastly, this will also help memcpy (in a coming hardening update) execute proper bounds-checking on variable length object i_symlink at fs/ocfs2/namei.c:1973: fs/ocfs2/namei.c: 1973 memcpy((char *) fe->id2.i_symlink, symname, l); Link: https://github.com/KSPP/linux/issues/21 Link: https://github.com/KSPP/linux/issues/193 Link: https://github.com/KSPP/linux/issues/197 Link: https://gcc.gnu.org/onlinedocs/gcc/Zero-Length.html Link: https://lkml.kernel.org/r/YxKY6O2hmdwNh8r8@work Signed-off-by: Gustavo A.

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.
