In D13786 only the version was updated somehow.
This patch actually updates the sources.

Changes for version 5.16 to 6.0.1 can be found here.

Create a new btrfs filesystem, mount and check it:

truncate -s 1G /tmp/test
mkfs.btrfs -L temp --checksum blake2 /tmp/test
sudo mount /tmp/test -o space_cache=v2 /mnt
sudo btrfs fi usage /mnt
sudo btrfs scrub start -Bd /mnt
