SUSE engineer David Sterba submitted the Btrfs pull request for Linux 6.19 on Friday, ahead of the Linux 6.18 stable kernel release that took place on Sunday. This copy-on-write file-system continues seeing some enticing feature work and other improvements for this next version of the Linux kernel.

With the Linux 6.18 kernel Btrfs added experimental support for block sizes greater than the page size. That “BS > PS” work continues being built out in Linux 6.19. The code now supports more operations when not using large folios, like encoded read/write and Btrfs SEND support. Btrfs’ native RAID5 / RAID6 support is also now able to handle the block size being greater than the page size.
