We expect caller to take a plug and send bio with source information,

Once the src bio arrives we form a request and wait for destination
bio. Upon arrival of destination we merge these two bio's and send
corresponding request down to device driver.

Is the above description up-to-date? In the cover letter there is a different description of how copy offloading works.

Thanks,

Bart.
