Watchdog pretimeout governors were enabled from the default governor selection using "select". As a result, the default governor was always built into the kernel, even if no watchdog driver was loaded. By using "depends on" instead of "select", we are in better control, and the governors can all be built as modules. At the same time, set the default configuration option for pretimeout governors to match WATCHDOG_CORE (meaning all pretimeout governors are by default enabled if pretimeout support is enabled). The practical impact of this change is minimal. Previously, selecting a default governor automatically enabled that governor. Now, a default governor can only be selected if that governor has been enabled. Consequently, the order of governor selection is now reversed: The governor selection is now first, followed by default governor selection.

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.
