... and document the constraints on the layout. Kept separate from the previous commit to keep the noise separate from actual changes. The reason for explicit __aligned() on ->name[] rather than relying upon the alignment of the previous field is that the previous iteration of that commit tried to save 4 bytes on 64bit by eliminating a hole in there, which broke the assumptions in dentry_string_cmp().

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.
