[PATCH] Don't #ifdef prototypes

[PATCH] Don't #ifdef prototypes

[Russell King]

It seems that changing CONFIG_BLK_DEV_INITRD causes the whole kernel to
rebuild due to an inappropriate ifdef in linux/fs.h - we should not
conditionalise prototypes.

In addition, real_root_dev is only used by two files (kernel/sysctl.c
and init/do_mounts_initrd.c) so it makes even less sense that it was in
linux/fs.h
