Data race condition

The value of the shared data will be determined by the interleaving of thread execution. Thread shared data is accessed without holding an appropriate lock, possibly causing a race condition
/src/mongo/util/concurrent_shared_values_map.h:75: MISSING_LOCK 152873 Accessing "this->_map" without holding lock "mongo::ConcurrentSharedValuesMap<boost::optional<mongo::TenantId>, mongo::PreImagesTenantMarkers>._mapModificationMutex". Elsewhere, "mongo::ConcurrentSharedValuesMap<boost::optional<mongo::TenantId>, mongo::PreImagesTenantMarkers>._map" is written to with "ConcurrentSharedValuesMap._mapModificationMutex" held 3 out of 3 times.
