F2FS File-System Major Linux 3.13 Enhancements
For those in need of a high-performance specially-optimized file-system for flash storage devices, the F2FS file-system developed at Samsung has seen more "major enhancements" queued up for the Linux 3.13 kernel.
Jaegeuk Kim at Samsung had his F2FS file-system update pulled over the night for the 3.13 kernel merge window. The F2FS Linux 3.13 major enhancements mentioned by the open-source developer with his F2FS pull include a new sysfs to control reclaiming free segments, enhancements to the F2FS global lock procedures, enhanced the victim selection flow, waiting for selected node blocks during fsync, new tracepoints, and a config to remove the abundant BUG_ONs. There's also other bug-fixes too.
During the Flash-Friendly File-System's tenure in the Linux kernel we have found the file-system to work great for SDHC storage, it also works good for USB flash drives, and it's running great on SSDs. New solid-state drive benchmarks of F2FS will come on the Linux 3.13 kernel once its merge window is closed and we'll proceed at Phoronix with the usual EXT4, XFS, F2FS, and Btrfs file-system performance benchmarks.
