I want to compile out proc_* and sysctl_* handlers totally and stub them to NULL depending on config options, however usage of & will prevent this, since taking adress of NULL pointer will break compilation. So, drop & in front of every ->proc_handler and every ->strategy handler, it was never needed in fact. Signed-off-by: Alexey Dobriyan <adobriyan@gmail.com> Signed-off-by: David S.
