Abstract
A locking scheme is provided to arbitrate thread access to file system objects. This locking scheme allows multiple threads simultaneous access to file system objects for certain concurrently compatible operations, while forbidding concurrently incompatible operations. Separate types of locks are provided for hierarchical relationships between objects and the contents (e.g., data) of the objects themselves.
