I don't see patch 2/4 in the mailinglist, probably over the 100kb limit.

The lib/* stuff needs to be merged first, I shouldn't add non-btrfs code
to our regular for-next branch. A testing branch with all the zstd code
can be created, but from the upstream merging process, I don't think we
can avoid two step merging.
