ZFS on Linux repo renamed to openzfs/ZFS

Awesome! Hopefully there will be some more activity on the pull requests as well, as there are a few nice features waiting so long to be included.

True, for example zstd support has been in the queue for ages

This is a much needed rebranding from zfsonlinux.

I don't get it. Is file system branding that important?

Branding and marketing is the most important thing in the universe for an open source project.

Can't tell if that is sincere or snarky. So, you win?

But, in all seriousness, why did this need to happen, and what is its significance, if any? Should I be trying to interpret it, or is it just "here's the new name, just so you know it's the same project when you hear aboit it"?

And how about zstd, anyway?

Does it still have a license that raises concerns about Oracle potentially squeezing users of zfs?

Can you resize a zpool yet?

Not as well as JFS2 nope.

Sure; you can grow it.
