You must fix the ARM code to handle this properly. blkback also uses grant maps and depending on the frontend blkback may grant map the same machine frame multiple time. We have see frontends that send such requests. I can't remember how the ARM code works. Where is the problematic m2p lookup? Perhaps this could be avoided for foreign frames?
