[ Upstream commit 48df133578c70185a95a49390d42df1996ddba2a ]
GCC does not like having a partially allocated object, since it cannot
reason about it for bounds checking when it is passed to other code.
Instead, fully allocate sig_inputArgs. (Alternatively, sig_inputArgs
should be defined as a struct coda_in_hdr, if it is actually not using
any other part of the union.) Seen under GCC 13:
../fs/coda/upcall.c: In function 'coda_upcall':
../fs/coda/upcall.c:801:22: warning: array subscript 'union inputArgs[0]' is partly outside array bounds of 'unsigned char[20]' [-Warray-bounds=]
801 | sig_inputArgs->ih.opcode = CODA_SIGNAL;

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.
