This is needed for building Rust bindings on big endian architectures like s390x. Currently this is only done in userspace, but it might happen in-kernel in the future. When creating a Rust binding for struct bkey, the "packed" attribute is needed to get a type with the correct member offsets in the big endian case. However, rustc does not allow types to have both a "packed" and "align" attribute. Thus, in order to get a Rust type compatible with the C type, we must omit the "aligned" attribute in C. This does not affect the struct's size or member offsets, only its toplevel alignment, which should be an acceptable impact. The little endian version can have the "align" attribute because the "packed" attr is redundant, and rust-bindgen will omit the "packed" attr when an "align" attr is present and it can do so without changing a type's layout Signed-off-by: Thomas Bertschinger <tahbertschinger@gmail.com> Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev> |

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.
