Compile error in vmlinux-2.4.19-rc1

In module init/do_mounts.c I get error "undefined symbol change_floppy" when CONFIG_BLK_DEV_RAM=y and CONFIG_BLK_DEV_FD=m. The error can be corrected with the following patch

381c381
< #if defined(CONFIG_BLOCK_DEV_RAM) || defined(CONFIG_BLK_DEV_FD)

best regards
