2.4.18 --> 2.4.19. Ramdisk requires floppy?

Hi,

I've noticed that the 2.4.19 version of "prepare_namespace"
(init/do_mounts.c) not allows you to mount a non floppy as a
ramdisk(?). This has changed since 2.4.18 (split of main.c ->
{do_mounts,main}.c).

2.4.18 does a very simple check (below):

--- 2.4.18 ---
#ifdef CONFIG_BLK_DEV_RAM
#ifdef CONFIG_BLK_DEV_INITRD
        if (mount_initrd)
                initrd_load();
        else
#endif
        rd_load();
#endif
--- 2.4.18 ---

however, in 2.4.19 it just tries to load a ramdisk if it's on a
floppy. Why? There may still be a ramdisk on an other device, NOT
using initrd.

--- 2.4.19 ---
if (mount_initrd) {
       if (initrd_load() && ROOT_DEV != MKDEV(RAMDISK_MAJOR, 0)) {
              handle_initrd();
              goto out;
       }
} else if (is_floppy && rd_doload && rd_load_disk(0))
       ROOT_DEV = MKDEV(RAMDISK_MAJOR, 0);
mount_root();
out:
--- 2.4.19 ---
