I certainly agree on that in general, but at the same time it makes the expected submission of bcachefs not having to carry a number of (essentially) unrelated patches. I'm assuming the likelihood of bcachefs being submitted soonish is high, hence we won't have exports that don't have in-kernel users in the longer term. -- Jens Axboe
