-The old "ramdisk=<ram_size>" has been changed to "ramdisk_size=<ram_size>" to
-make it clearer. The original "ramdisk=<ram_size>" has been kept around for
-compatibility reasons, but it may be removed in the future.
-There are also config symbols (in the Block drivers config menu) for these
-variables: BLK_DEV_RAM_SIZE defaults to 4096 and BLK_DEV_RAM_BLOCKSIZE
-defaults to 1024.
