F2FS Sees Nice Set Of Enhancements For Linux 6.15
In addition to the Btrfs updates with real-time Zstd compression support and Bcachefs stabilizing its on-disk format, the Flash Friendly File-System updates have also been submitted already for the newly-opened Linux 6.15 merge window
F2FS this cycle saw work on converting to make use of folios as well as seeing performance optimization work around direct I/O when overwriting data, faster checkpoints via higher priority I/O, and adding a kernel ioctl to get the I/O priority hint. Enhancement: - huge folio converion work by Matthew Wilcox - clean up for mount API conversion by Eric Sandeen - improve direct IO speed in the overwrite case - add some sanity check on node consistency - set highest IO priority for checkpoint thread - keep POSIX_FADV_NOREUSE ranges and add sysfs entry to reclaim pages - add ioctl to get IO priority hint - add carve_out sysfs node for fsstat See this pull request for the full list of patches pending for the Linux 6.15 merge window.
