hesela.devSMB opportunistic lock
An SMB opportunistic lock is a revocable server-granted caching arrangement that lets a client reduce network operations while coordinating access to a file.
Oplocks coordinate cache use; they are not application byte-range locks. [1] Classic SMB2 oplock levels and leases have distinct request encodings: a lease requires its create context, and its request level is invalid for SMB 2.0.2. [2] Do not assume every break needs an acknowledgement: the level-II-to-none transition does not. [3] These caching arrangements do not by themselves acknowledge durable data storage.
