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/db/s/range_deleter_service.cpp:188: MISSING_LOCK 144237 Accessing "this->_threadOpCtxHolder" without holding lock "mongo::RangeDeleterService::ReadyRangeDeletionsProcessor._mutex". Elsewhere, "mongo::RangeDeleterService::ReadyRangeDeletionsProcessor._threadOpCtxHolder" is written to with "ReadyRangeDeletionsProcessor._mutex" held 2 out of 2 times.
