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

7 | See Documentation/kernel-parameters.txt for information on | |
8 | providing kernel parameters for builtin drivers versus loadable | |
