摘要： Systems and methods for inode use are presented. In one embodiment; an inode reuse method includes: receiving an indication of an operation that involves access to file related information; assigning an inode to the access; identifying one of a plurality of inode reuse scenarios for the inode; and making the inode available for reuse in accordance with the one of the plurality of inode reuse scenarios. In one embodiment, the one of the plurality of inode reuse scenarios is a relatively expedited reuse scenario. In one exemplary implementation, the relatively expedited inode reuse scenario is utilized if the inode is not required for further processing associated with the operation. The inode can be reused for another immediately subsequent operation. In one embodiment, a first one of the plurality of inode reuse scenarios includes placing the inode at a head queue position of a use queue and a second one of the plurality of inode reuse scenarios includes placing the inode in a tail queue position of the use queue. Association of the inode to the inode reuse scenario can be tracked. The tracking can include flagging the inode for relatively expedited reuse.

摘要： Various systems and methods for partitioning a directory while allowing concurrent access to the directory. For example, a method involves receiving a request to partition an original directory that comprises a plurality of entries and creating a partitioned directory in response to receiving the request. The method also involves distributing the entries from the original directory to the partitioned directory. Distributing the entries involves sequentially copying each entry from the original directory to the partitioned directory. The method also involves performing an operation on the original directory while the entries are being distributed. Performing the operation involves accessing and/or updating the original directory.
