Abstract

Improved methods and systems for granular opportunistic locking mechanisms (oplocks) are provided for increasing file caching efficiency. Oplocks can be specified with a combination of three possible granular caching intentions: read, write, and/or handle. An oplock can be specified with an identifier that indicates a client/specific caller to avoid breaking the original oplock due to an incompatibility from other requests of the same client. An atomic oplock flag is added to create operations that allow callers to request an atomic open with an oplock with a given file.
