Interesting decision they made, I wonder whether they would decide differently now after seeing all the complexity.

So Rust does not decrease the complexity, but only removes certain kinds of errors which the compiler can detect. Neither logic errors nor speed regressions.

Thank you for your input.

Decide what? Cow is a fundamental part of how btrfs works, and Rust didn't exist for the majority of Linux's life. (Although if you're into that, look at Redox)

Sorry I was unclear :) Maybe they would limit storage to 90% now, seeing that it increases complexity. Maybe I misunderstood the prior point though.

Thanks fr mentioning Redox!
