I thought about this for a moment. Since the return value should also
be used for the corresponding sysctl, which is an integer, I wasn't
sure if bool is the correct type, especially since other boolean
functions in kexec.h also return int... But that could be legacy.

I've got no problem changing the type to 'bool' if that's what it takes.
