This is unfortunate but not exactly surprising, I've quite liked bcachefs for its features but I swear every release has been accompanied by issues with Kent expecting exceptions to standard procedure be made for bcachefs. When you manage an open source project as big as Linux that's just not sustainable, and it's frustrating to see Kent not recognise why the onus is on him to make the necessary accommodations.

Ken overstreet:

I positively enjoy working with you - when you're not being a dick, but you can be genuinely impossible sometimes. A lot of times...

Where does he expect this to go?

"Oh, well in that case I guess you're part of the kernel again"

?

He seems like he has a savior complex. I don't blame the kernel maintainers for wanting to avoid working with him.
