Vincent Mailhol <mailhol.vincent@wanadoo.fr> says: ==================== The c_can, flexcan and slcan use a setter function to populate net_device::ethtool_ops. Using a setter here add one additional function call and add some small bloat in the object file. Exporting the structure allow to remove this setter. The mcp251xfd uses a similar pattern except that it does some additional initialization. As such, this driver is left untouched. * Statistics * For the slcan driver, this patch reduces the object file by 14 bytes (details in the first patch). Although we did not conduct a benchmark for the other drivers but we expect the exact same figures. ==================== Link: https://lore.kernel.org/all/20220727104939.279022-1-mailhol.vincent@wanadoo.fr Signed-off-by: Marc Kleine-Budde <mkl@pengutronix.de>
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.
