Abstract
The system described herein introduces a cache that a file system uses to determine, for a current object, if the process to merge different types of access control information into merged access control information has already been performed for a previous object. Stated alternatively, the file system uses the cache to determine whether a current object being processed for storage has the same combination of access control information as a previous object that has already been processed for storage. If the current object has the same combination of access control information as the previous object, the file system is able to associate merged access control information for the previous object with the current object via the use of a pointer. Consequently, the file system avoids having to perform the resource-intensive process of merging the different types of access control information for the current object.
