docs: document panic fully in sysctl/kernel.rst (404347e6) · Commits · 戴 / test

The description of panic doesn’t cover all the supported scenarios; this patch fixes that, describing the three possibilities (no reboot, immediate reboot, reboot after a delay). Based on the implementation in kernel/panic.c. Signed-off-by:

		=====

		The value in this file represents the number of seconds the kernel
		waits before rebooting on a panic. When you use the software watchdog,
		the recommended setting is 60.
		The value in this file determines the behaviour of the kernel on a
		panic:

		* if zero, the kernel will loop forever;
		* if negative, the kernel will reboot immediately;
		* if positive, the kernel will reboot after the corresponding number
		of seconds.

		When you use the software watchdog, the recommended setting is 60.
