-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/kernel-parameters.txt for information on
-providing kernel parameters for builtin drivers versus loadable
-modules.
