F2FS, the promising "Flash Friendly" file-system developed at Samsung and has shown promising performance results on various flash devices, has seen more improvements with the Linux 3.10 kernel.

Per the F2FS 3.10 merge, prominent changes for this experimental file-system in the Linux 3.10 kernel include:

- Introduce a new global lock scheme.
- Add tracepoints on several major functions.
- Fix the overall cleaning process focused on victim selection.
- Apply the block plugging to merge IOs as much as possible
- Enhance management of free nids and its list.
- Enhance the readahead mode for node pages.
- Address several critical deadlock conditions.
- Reduce lock_page calls.

These are just what Samsung's Jaegeuk Kim describes as the major 3.10 changes, there's also smaller bug-fixes and enhancements too. New F2FS file-system benchmarks from this next version of the Linux kernel will come soon on Phoronix.
