Ok, then what's the purpose of those messages?
:        pr_notice("random: %d get_random_xx warning(s) missed "
:                  "due to ratelimiting\n",
:                  unseeded_warning.missed);
:        pr_notice("random: %d urandom warning(s) missed "
:                  "due to ratelimiting\n",
:                  urandom_warning.missed);

I thought you want to print the summary after initializing random,
not once per second?
