Hello,
I believe you'll break the "chain" if you return an error. You might
have registered as the last
one so probably nothing would break but if someone registers on the
notifier after your module
did then that won't receive the notification if you throw an error and
break the chain.
Regards,
Hi
There is such struct as 'notifier_block'. It has member 'notifier_call'
where You assign pointer to your function (handler) and priority. Then You
register such notifier block to restart handler list.
Then when You type in linux reboot Your function might be invoked (depends
on priority you set
