IOCTL_BLKSNAP_SNAPSHOT_APPEND_FILE

Description
It seems to me that a special request 'IOCTL_BLKSNAP_SNAPSHOT_APPEND_FILE', similar to the request 'IOCTL_BLKSNAP_SNAPSHOT_APPEND_STORAGE', can be made. The input parameter for it will be a file descriptor (as for the loop devices). The module will keep it in exclusive access.
