Rethink about this, you are right. Using BUILD_BUG_ON is better. Anyone who found this compiling break should check if his/her code changes increase the crash_notes size. If possible that increase need be avoidable. Otherwise he should report this to upstream why it's unavoidable to increase crash_notes size, then let's consider the redesign the crash_notes data structure. So I will use BUILD_BUG_ON and repost.
