Roger Pau Monne bfe11d6de1 xen-blkfront: restore the non-persistent data path ... When persistent grants were added they were always used, even if the backend doesn't have this feature (there's no harm in always using the same set of pages). This restores the old data path when the backend doesn't have persistent grants, removing the burden of doing a memcpy when it is not actually needed.
