Abstract

Techniques are provided for tracking users modifying, writing, or editing a file. In an example, a file system maintains a first-in-first-out queue that logs a finite set of users that have most-recently modified a file. This queue can be maintained in an extended attribute of an Mode that corresponds to a file. Where a user modifies a file, and the user is currently identified in the queue, the user can be removed from the queue. Where the user modifies a file, is not currently identified in the queue, and the queue is full, an oldest user in the queue can be removed from the queue. Then, the user can be added to the back of the queue.
