--- Comment #3 from Jinoh Kang <jinoh.kang.kr at gmail.com> ---
I'm afraid you might have mistaken, since the patch (particulary the test)
refers to *both* unsuffixed (\Device\NamedPipe) and suffixed
(\Device\NamedPipe\) versions of the named pipe device path.

Also note that it is not possible to use \Device\NamedPipe (no trailing
backslash) as RootDirectory for new named pipes at all (it will fail with
STATUS_OBJECT_NAME_INVALID).
