The following ext4 bug fixes and features have been implemented in this update:

  • Code updated to introduce support for direct access (DAX) page operations on Non-Volatile Dual Inline Memory Modules (NVDIMMs) using the ext4 file system.

  • A bug was fixed to resolve an issue that could cause a corrupted file system if a direct write extended beyond the i_disksize but is less than the i_size.
