9b1fe05104On x86_64 and allmodconfig, this shrinks the size of 'struct regmap_config' from 328 to 312 bytes. This is usually a win, because this structure is used as a static global variable. When moving the kerneldoc fields, I've tried to keep the layout as consistent as possible, which is not really easy! Before: /* size: 328, cachelines: 6, members: 55 */ /* sum members: 296, holes: 6, sum holes: 25 */ /* padding: 7 */ /* last cacheline: 8 bytes */ After: /* size: 312, cachelines: 5, members: 55 */ /* sum members: 296, holes: 5, sum holes: 16 */ /* last cacheline: 56 bytes */ For the records, this is also widely used: $git grep static.*regmap_config | wc -l 1327 Signed-off-by: Christophe JAILLET <christophe.jaillet@wanadoo.fr> Link: https://lore.kernel.org/r/5e039cd8fe415dd7ab3169948c08a5311db9fb9a.1715024007.git.christophe.jaillet@wanadoo.fr Signed-off-by: Mark Brown <broonie@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.
