Phoronix: Btrfs Gets Some Buttery Good Improvements With Linux 5.19

David Sterba of SUSE has submitted the ~4k lines of code worth of feature changes for the Btrfs file-system driver in the Linux 5.19 kernel...

What about bugfixes too?

[Quackdoc]

a little off topic, is there a decent solution for when you delete files you don't regain the space properly instead of setting a job to periodically do it?

What about bugfixes too?

Fixes: - fix count of reserved transaction items for various inode operations
- fix deadlock between concurrent dio writes when low on free data space
- fix a few cases when zones need to be finished
- fix sync operations to lower saturated fat levels

So will the disk format stay the same or do we have to format it again to use new features?

There is nothing in the PR that suggests remotely the requirement of a format change. Filesystems rarely change it and advertise it widely when there is a need.

If you don't drastically change the filesystem usage (chance from tons of snapshots and files to only a subvolume with big files) this isn't really an issue in the last 6+ years.

Too bad nobody is upgrading also the Zstd code to the latest upstream version so people who use BTRFS+Zstd compression enjoy the best performance.
I'm thinking that even some of the Steam Deck users might use this combination to mitigate the small storage space compared to the game sizes nowadays.

The Deck only uses BTRFS for the system partition; not to store games. For its /home it uses ext4 with case insensitivity enabled since both game mods and Windows programs benefit from it. Insensitivity really helps with extracting archives made on Windows and some Windows programs can greatly slow down on case sensitive file systems.

There's a file system that shall not be named that offers both Zstd and insensitivity.
