![FREE SOFTWARE](/assets/categories/freesoftware.webp)
Changes for the F2FS file-system with Linux 3.15 include the introduction of support for large directories, performance improvements for some server workloads, new sysfs entries for better tuning F2FS configurations, and several bug-fixes.
In total there's just under one thousand lines of new F2FS file-system code for the Linux 3.15 merge window. The pull request, which was sent in on late Sunday night, can be viewed via the IU.edu kernel archive. With the Btrfs and EXT4 and Btrfs file-system changes have already been merged to mainline, in the days ahead when the kernel code churn lightens up, we'll have out some fresh Linux file-system benchmarks from hard drives and solid-state drives of these major open-source file-systems.
