There's additional complexity here: if the request isn't prepared, no command is allocated. You can't use the one you have because it belongs to a different device (plus it would be freed by this request in the completion path). > Blk_rq_map_kern() > Blk_execute_req_nowait() If the request is already mapped, you don't want to be mapping it again. > Blk_put_request() Without seeing the code it's hard to say definitively whether all this is correct.
