* include/device/device_types.h: New get_status call DEV_GET_RECORDS to get the number of records of a device (rather than the number of bytes). Accordingly define DEV_GET_RECORDS_DEVICE_RECORDS, DEV_GET_RECORDS_RECORD_SIZE and DEV_GET_RECORDS_COUNT. * linux/dev/glue/block.c (device_get_status): Handle DEV_GET_RECORDS.
