Russell King says: ==================== Add mdiobus_modify_changed() helper Sean Anderson's recent patch series is introducing more read-write operations on the MDIO bus that only need to happen if a change is being made. We have similar logic in __mdiobus_modify_changed(), but we didn't add its correponding locked variant mdiobus_modify_changed() as we had very few users. Now that we are getting more, let's add the helper. ==================== Link: https://lore.kernel.org/r/YV2UIa2eU+UjmWaE@shell.armlinux.org.uk 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 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.
