The Flash-Friendly File-System (F2FS) has been running well in our latest SSD benchmarks but with the forthcoming Linux 3.18 kernel it's going to be in even better shape.

Jaegeuk Kim, formerly of Samsung, sent in his F2FS pull request on Wednesday for the 3.18 merge window. Features of the F2FS file-system with this next kernel include support for large sector sizes, FITRIM support, and atomic/volatile writes. There's also enhancements to the check-point speed and roll-forward speed. F2FS for Linux 3.18 also retains some recovery information from fsck.f2fs, enhances the flush command management, fixes a bug in lseek, tunes in-place-update policies, and revisits all the roll-forward and fsync rules.

More details via the F2FS pull request with this update touching around one thousand lines of code. Once Linux 3.18 is out in release candidate form we'll be back around with our frequent F2FS, EXT4, Btrfs, and XFS file-system benchmarking.
