Use the bark interrupt as the pretimeout notifier if available. When the watchdog timer expires in dual mode, an interrupt will be triggered first, then the timing restarts. The reset signal will be initiated when the timer expires again. The pretimeout notification shall occur at timeout-sec/2. V2: - panic() by default if WATCHDOG_PRETIMEOUT_GOV is not enabled. V3: - Modify the pretimeout behavior, manually reset after the pretimeout - is processed and wait until timeout. V4: - Remove pretimeout related processing. - Add dual mode control separately. V5: - Fix some formatting and printing problems. V6: - Realize pretimeout processing through dualmode. V7: - Add set_pretimeout(). V8/V9: - Fix some formatting problems.

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.
