SUSE engineer Qu Wenruo has been working through huge folios support for Btrfs to support up to a 2MB folio size. Similar to the large folios, huge folios can help Btrfs in achieving greater I/O throughput and reduced system overhead while providing for better memory management. The patches introducing huge folios for Btrfs have made it into David Sterba's kdave/linux.git's for-next Git branch.
