F2FS Gains New Features With Linux 3.17

The Samsung supported Flash-Friendly File-System (F2FS) will sport some new functionality with the Linux 3.17 kernel release.

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.
