I don't think that's needed - If CONFIG_TMPFS isn't set, then ramfs
pretends to be tmpfs anyway, see mm/shmem.c:
static struct file_system_type tmpfs_fs_type = {
.name = "tmpfs",
.get_sb = ramfs_get_sb,
.kill_sb = kill_litter_super,
};
So calling it tmpfs isn't really wrong.

We can change the help text to say tmpfs/ramfs if you prefer - OK?
