WatchDog Module Parameters
==========================

This file provides information on the module parameters of many of
the Linux watchdog drivers.  Watchdog driver parameter specs should
be listed here unless the driver has its own driver-specific information
file.

See Documentation/admin-guide/kernel-parameters.rst for information on
providing kernel parameters for builtin drivers versus loadable
modules.
