[AsyncAwait]

You're just ignoring what I said above. Nobody is out to screw ZoL, but the kernel community doesn't care enough to maintain compatibility with it.

Why, as a kernel dev, would you care if there's no possibility of it ever being mainlined because of decisions Sun explicitly made to be hostile towards your project?

It's like trying to cozy up to someone who just punched me, not happening.

Bcachefs isn't yet up to parity for sure, but it is stable enough for everyday use and doesn't corrupt you data like Btrfs sometimes does. A stable foundation that gets expanded upon daily.
