I'm saying that "Hey, if you are unsure > you want 'N'" is a good thing to say, but removing the description of > "what configfs is" is unhelpful and unneeded. OK, what about the patch below? > Joel cu Adrian <-- snip --> Make it clear that users usually shouldn't manually enable CONFIGFS_FS.

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.

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