This avoids copying the IV twice for each operation.

Event Timeline

Does this mean that crd_iv potentially contains unknown data ? E.g. after the partial copy + fault.

Perhaps it is fine because the content of crd_iv is user-controlled anyway.

crd_iv is only used after the copyin() if it succeeds. It shouldn't have any different data as a result of this change once a request is submitted to the driver.
