Zstandard v1.5.0

Is this the same "zstd" compression used in Fedora's btrfs transparent block level compression? I have been thoroughly impressed with it in Fedora 34. If that's true, I had no idea that it was a Facebook project. Color me shocked.

Yeah, it is.

The Linux kernel is currently using zstd-1.3.1, and I'm working on getting it updated to the latest zstd version.

Looking forward to having modern zstd in-kernel! Thanks for your efforts.

According to https://en.wikipedia.org/wiki/Btrfs the core developers of brtfs work at Facebook.

> In June 2012, Chris Mason left Oracle for Fusion-io, which he left a year later with Josef Bacik to join Facebook. While at both companies, Mason continued his work on Btrfs.[27][17]

It wasn't originally. Facebook hired Yann Collet well after zstd was a working thing.

Facebook actually does a decent amount of work on Fedora, and were even part of the force behind using btrfs as the default.
