I see how this fixes the problem, but this doesn't seem like an ideal
solution. The fact that the *_ssr_notifier() functions are correctly protected
by conditional compilation ideally should mean that clients don't need to call
call out this as a dependency. Otherwise, it would mean we'd need to do this
for all feature flags.
+linux-kbuild just to make sure there isn't a better approach.
