Description

Debugging some issues is much, much easier if we know the recent set of IOs that have
come through the system. We could add a small ring buffer that just recorded
ds_id, IO type, offset, size, timestamp.

Maybe when a task receives the OP and then again on completion?
Maybe for each downstairs client.
