The user-facing work found with the F2FS file-system for Linux 3.17 includes the major following work:
- A nobarrier mount option has been added to F2FS, similar to other file-systems. With this option the file-system keeps the I/O ordering but ignores information about cache flushes inside the storages.
- Support for the tmpfile() function to create a unique temporary file in binary read/write mode that deletes itself when the program ends.
- Support for the rename2() function.
- Enhanced fdatasync().
- Various fixes and other improvements.
