--- Comment #1 from Roger Pau Monné <royger at freebsd.org> ---
I've already told Wei that creating your own bounce buffer is a bad idea.
Instead you should use the BUSDMA API and let it take care of the bouncing when


IIRC something was missing in BUSDMA so that the HyperV storage driver could
use it, we should look into adding what's needed and then removing this custom
bounce buffering.

Please upload the patch to the review system.
