Looking at the code, I see that it's no longer the case.

Oh, I see. That looks like some old, out of date version of the docs.
The text was already correct in 5.15, it seems:

https://elixir.bootlin.com/linux/v5.15/source/fs/debugfs/inode.c#L549

Also this render of the docs is correct:

https://www.kernel.org/doc/html/latest/filesystems/api-summary.html#c.debugfs_create_dir

I don't really know who's responsible for the kernel.org docs... 
Let's CC Jon.

Jon, is the www.kernel.org/doc/htmldocs/ copy intentionally what it is?
Anyone we should talk to?
