I'm not concern about failure of sysfs operations.
In panic function call, panic_notifier_chain is kicked. Also users may expect the system reboots in panic case
by specifying /proc/sys/kernel/panic.

I just would like to avoid failures of those operations without adding unnecessary calls in the write callback.

Thank you for your suggestion. I will update my patch by adding this logic above.
