Abstract
Avoiding data conflicts includes initiating a transactional lock elision transaction containing a critical section, executing the transactional lock elision transaction including the critical section, and checking a status of a lock prior to a commit point in the transactional lock elision transaction executing, wherein the checking the status occurs after processing the critical section. A determination of whether the status of the lock checked is free is made and, responsive to a determination the lock checked is free, a result of the transactional lock elision transaction is committed.
