Kostik (kib) suggested a possible valid use-case that depends on the current
order: adding dynamic sysctl-s under static sysctl-s via the module load 
He also offered an idea for a possible solution: holding the modules lock in the
shared mode (MOD_SLOCK) around calls to sysctl-s registered from modules.
