Problem that such things start to spread all over the kernel with a copy-paste approach if there is nobody to clean up the code. This is not a common convention and sometimes it's getting corrected [1]. [1] https://git.kernel.org/linus/6d7434931

I'll try not to forget to come back to this later on.

There is no need to annotate function prototypes with 'extern', it makes code less readable. Remove unnecessary annotations from <reboot.h>.
