Once upon a time nfp_cpp_resource_find() took a name parameter,
which could be any user-chosen string. Resources are identified
by a CRC32 hash of a 8 byte string, so we had to pad user input
with zeros to make sure CRC32 gave the correct result.
Since then nfp_cpp_resource_find() was made to operate on allocated
resources only (struct nfp_resource). We kzalloc those so there is
no need to pad the strings and use memcmp.
This avoids a GCC 8 stringop-truncation warning:
In function ‘nfp_cpp_resource_find’,
inlined from ‘nfp_resource_try_acquire’ at .../nfpcore/nfp_resource.c:153:8,
inlined from ‘nfp_resource_acquire’ at .../nfpcore/nfp_resource.c:206:9:
.../nfpcore/nfp_resource.c:108:2: warning: strncpy’ output may be truncated copying 8 bytes from a string of length 8 [-Wstringop-truncation]
strncpy(name_pad, res->name, sizeof(name_pad));

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
