reboot too. Another solution would be to unregister the reboot_notifier in the reboot_nofifier itself. I've just seen one watchdog driver (drivers/rtc/rtc-m41t80.c) which does that. But I still think such
That, btw. is broken. ;)
Right after having send the mail, I've became that intuition, had a look and ... notifier.h does state the following:
* atomic_notifier_chain_unregister(), blocking_notifier_chain_unregister(), * and srcu_notifier_chain_unregister() _must not_ be called from within * the call chain.
(The reboot-notifier chain is of type blocking_notifier_chain)
So I've picked up one user of reboot_notifier by random and had the luck to choose a broken one. ;)
I will make a patch and will have a look if the same failure can be found elsewhere. There aren't that much users of the reboot-notifier, so it shouldn't cost me that much time.
