This looks like a big mess, and usage of phys_to_virt is not generally safe to start with. If HyperV really is that broken the warning seems correct, but if you really have to get rid of it we could add a blist flag to not issue the warning in the core code instead of hacking around it in the driver. -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
