As pages should never be discarded unless something went wrong, let's only
print that if there were discarded pages.
if (discarded) {
pr_info("Ring buffer meta [%d] is from previous boot! (%d pages
discarded)\n",
cpu_buffer->cpu, discarded);
} else {
pr_info("Ring buffer meta [%d] is from previous boot!\n",
cpu_buffer->cpu);
}
