Abstract
A lock for managing shared resources in a data processing system enables a requesting processor, in a signal atomic transaction, to validate the main lock data structure, request a lock, take the lock and establish a lock mode if successful, or establish its place in a queue of requesters for subsequent locks on the shared resource if unsuccessful.
