Feature #1480
Updated by Greg Farnum almost 12 years ago
Implement cooperative locking of RBD images (coordinated on the header, of course). Write public class functions to support both exclusive and shared locking, to list lock holders, and to let third parties remove locks. Then implement corresponding librbd functions, and write tests for the new functionality.
Support having multiple locks from the same entity (ie, multiple VMs on the same KVM host) by storing lockers as both the entity and a request-defined cookie.
