Subject: [RFC] A question about sysctl

hi all,

When doing FUZZ test with strict writes enabled:
 - $ 80 00 > /proc/sys/kernel/hung_task_timeout_secs
 - $ cat /proc/sys/kernel/hung_task_timeout_secs
 - $ 80

I have a silly question about this:
Should we return -EINVAL in this case both for strict writes enabled and disabled?

Thanks
