Jacob Keller says: ==================== packing: various improvements and KUnit tests This series contains a handful of improvements and fixes for the packing library, including the addition of KUnit tests. There are two major changes which might be considered bug fixes: 1) The library is updated to handle arbitrary buffer lengths, fixing undefined behavior when operating on buffers which are not a multiple of 4 bytes. 2) The behavior of QUIRK_MSB_ON_THE_RIGHT is fixed to match the intended behavior when operating on packings that are not byte aligned. These are not sent to net because no driver currently depends on this behavior. For (1), the existing users of the packing API all operate on buffers which are multiples of 4-bytes. For (2), no driver currently uses QUIRK_MSB_ON_THE_RIGHT. The incorrect behavior was found while writing KUnit tests. This series also includes a handful of minor cleanups from Vladimir, as well as a change to introduce a separated pack() and unpack() API. This API is not (yet) used by a driver, but is the first step in implementing pack_fields() and unpack_fields() which will be used in future changes for the ice driver and changes Vladimir has in progress for other drivers using the packing API. This series is part 1 of a 2-part series for implementing use of lib/packing in the ice driver. The 2nd part includes a new pack_fields() and unpack_fields() implementation inspired by the ice driver's existing bit packing code. It is built on top of the split pack() and unpack() code. Additionally, the KUnit tests are built on top of pack() and unpack(), based on original selftests written by Vladimir. Fitting the entire library changes and drivers changes into a single series exceeded the usual series limits. v1: https://lore.kernel.org/r/20240930-packing-kunit-tests-and-split-pack-unpack-v1-0-94b1f04aca85@intel.com ==================== Link: https://patch.msgid.link/20241002-packing-kunit-tests-and-split-pack-unpack-v2-0-8373e551eae3@intel.com Signed-off-by: Jakub Kicinski <kuba@kernel.org> |

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 reStructuredText 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.
