The naming convention shown in the page was ancient.
Now, the page is consistent with Documentation/devices.txt

The current text reflects the general worry in the kernel about
recipients of O_PATH fds being able to hardlink the referenced
files. It turns out that it was possible to link these files
regardless of any possible security concerns.
Linux 3.11 removes the capability check in AT_EMPTY_PATH.
I expect that this functionality will be generally useful,
so let's document it better.

* Using large buffer sizes for read(2) is orthogonal to the
discussion of variable-length event structures.
* Move the discussion of the read() return value to follow
discussion of what the read() actually returns in its buffer.
* Related rewordings.

Update as per http://www.spinics.net/lists/linux-man/msg05624.html
