/src/mongo/db/global_catalog/ddl/refine_collection_shard_key_coordinator.cpp:269: ATOMICITY 184172 Unlocking "this->this->_docMutex". "ns" might now be unreliable because other threads can now change the data that it depends on.

/src/mongo/db/global_catalog/ddl/refine_collection_shard_key_coordinator.cpp:270: ATOMICITY 184172 Using an unreliable value of "ns" inside the second locked section. If the data that "ns" depends on was changed by another thread, this use might be incorrect.
