This small series fixes is_madv_discard() and adds a small sanity check test to selftests/mm/mseal_test. Without this patch, is_madv_discard() erroneously thinks innocent ops like MADV_RANDOM are discard operations (which they are not, and are supposed to be allowed, per the overall design). Based on Linus's tree and taken from my mseal depessimization series[1].
