Hi all, This patch set imports the upstream kernel zstd library, patches it to work in grub, adds zstd support to the btrfs module, and adds a test case. I've separated the importing and patching of the upstream kernel zstd library for ease of review.
Thanks to David Sterba for starting this project! I started my patch from where he left off.
