When compiling with gcc version 14.0.1 20240116 (experimental)
and W=1, I've noticed the following warning:
block/bio-integrity.c: In function 'bio_integrity_map_user':
block/bio-integrity.c:339:38: warning: 'kcalloc' sizes specified with 'sizeof'
in the earlier argument and not in the later argument [-Wcalloc-transposed-args]
339 | bvec = kcalloc(sizeof(*bvec), nr_vecs, GFP_KERNEL);
| ^
block/bio-integrity.c:339:38: note: earlier argument should specify number of
elements, later size of each element
Since 'n' and 'size' arguments of 'kcalloc()' are multiplied to
calculate the final size, their actual order doesn't affect the
result and so this is not a bug. But it's still worth to fix it.
Fixes: 492c5d4559 ("block: bio-integrity: directly map user buffers")

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.
