The following XFS features have been implemented:

  • The new directory entry file type improves the performance of directory recursion by not having to access the inode data from disk.

  • Namespace support.

  • Defragmentation support for the new CRC file system format.

  • The XFS v5 disk format provides metadata CRC, object back references, better crash recovery, and improved xfs_repair performance. The metadata CRC feature is experimental and not currently supported.
