Oh, except you probably wouldn't have seen it, because Jens replied to
the original message where you weren't cc'd.

So here's the context for you wrt the other parts of the report:

  https://lore.kernel.org/all/4321724d-9a24-926c-5d2d-5d5d902bda72@kernel.dk/

where there isn't that same indirection through the super-block, but
more of a clear-cut "this is all in the block layer".
