[Bug 1835660] Re: initramfs unpacking failed

Has this to do with BLK_DEV_RAM being compiled as a module? From
init/initramfs.c:

> if (IS_ENABLED(CONFIG_BLK_DEV_RAM))
> printk(KERN_INFO "Trying to unpack rootfs image as initramfs...\n");
> else
> printk(KERN_INFO "Unpacking initramfs...\n");

> err = unpack_to_rootfs((char *)initrd_start, initrd_end - initrd_start);
> if (err) {
>#ifdef CONFIG_BLK_DEV_RAM
> populate_initrd_image(err);
>#else
> printk(KERN_EMERG "Initramfs unpacking failed: %s\n", err);
