It's a kernel config path. In meta branch for repo linux-yocto-3.14: commit 183622e8095545999a64bd72adedea2dffb6ec4b Author: Kevin Hao <kexin.hao@windriver.com> Date: Fri May 23 14:41:35 2014 +0800 beaglebone: enable the nowayout option for the watchdog The default watchdog behaviour is to stop the timer if the process managing it closes the file /dev/watchdog. The system would not reboot if watchdog daemon crashes due to a bug in it or get killed by other malicious code. So we prefer to enable nowayout option for the watchdong. With this enabled, there is no way of disabling the watchdog once it has been started. This option is also enabled in the predecessor of this BSP (beagleboard).
