| 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. |
