I agree. All the same I managed to read the whole article trying to understand the technical problems (which are far from trivial to see through) wondering until the end what GFP would be standing for... and finally googled it. Then I slapped my head.
But I think me being a stupid human being is not central here. The aim with documentation should be to make it as easy as possible for the reader to understand the technical issues and from that standpoint and this LWN article joining the "reference documentation" I think updating the article would be a good thing to do.
