Abstract
A deadlock prevention mode indicator is provided, wherein the deadlock prevention mode indicator is a lock that can be held in a shared mode or in an exclusive mode by one or more of a plurality of threads, and wherein the plurality of threads can cause deadlocks while acquiring a plurality of data locks. An execution of the plurality of threads is serialized by allowing a data lock to be acquired by a thread in response to the thread holding the deadlock prevention mode indicator, wherein serializing the plurality of threads avoids any deadlock from occurring.
