F2FS File-System Gets Discard Improvements, Nobarrier Fsync Mode For Linux 4.18

Flash-Friendly File-System (F2FS) maintainer Jaegeuk Kim has submitted the file-system updates intended for the Linux 4.18 kernel.

This flash storage optimized file-system has improvements around its discard/fstrim support, including the splitting of large discard commands for better responsiveness. There is also a new fsync_mode=nobarrier mount option available for reducing the number of cache flushes.

F2FS for Linux 4.18 also has improved sanity checks, various code clean-ups, and at least six known bug fixes.

The complete list of F2FS file-system changes for Linux 4.18 can be found via the kernel mailing list.
