Ack.
Thanks for this I was under the mistaken impression that FUA requests got split
by core dm into separate payload and PREFLUSH requests.
I've audited dm-cache and that looks ok.

the block was previously unallocated or because we are breaking sharing,
if the whole block of data is being overwritten the bio that triggered
the provisioning is issued immediately, skipping copying or zeroing of
the data bloc
