OK, what about the patch below?

Make it clear that users usually shouldn't manually enable CONFIGFS_FS.

config CONFIGFS_FS
tristate "Userspace-driven configuration filesystem (EXPERIMENTAL)"
depends on EXPERIMENTAL
help
configfs is a ram-based filesystem that provides the converse
of sysfs's functionality. Where sysfs is a filesystem-based
view of kernel objects, configfs is a filesystem-based manager
of kernel objects, or config_items.

Both sysfs and configfs can and should exist together on the
same system. One is not a replacement for the other.

+ This option is provided for the case where no in-kernel-tree
+ modules require configfs, but a module built outside the kernel
+ tree does. Such modules require Y or M here.
+
+ If unsure, say N.

config RELAYFS_FS
tristate "Relayfs file system support"
---help---
Relayfs is a high-speed data relay filesystem designed to provide
an efficient mechanism for tools and facilities to relay large
amounts of data from kernel space to user space.

To compile this code as a module, choose M here: the module will be
called relayfs.

If unsure, say N.
