Nack. The current behaviour of the *_namelen() functions is the
intended one. Their purpose is not for doing partial matches, but
instead for doing exact matches, but using a non-null-terminated
string as the argument. For example get_subnode_offset_namelen() is
used internally for comparing names against path components without
having to copy and null terminate the pieces of the path first.
