Since 5.10 kernel there is a new feature called fast_commit. In arch wiki https://wiki.archlinux.org/title/ext4 you can read that it can be enabled in existing filesystem with:
tune2fs -O fast_commit /dev/drivepartition
but in https://lwn.net/Articles/842385/ there is:
Fast commits are activated at filesystem creation time, so users will have to recreate their filesystems to use this feature.
tune2fs -O fast_commit truly enable this feature in existing filesystem ?
