I think it's read and write, but I think the naming is highly unfortunate. I started dabbling around with the patches a bit, and to keep my sanity a started reaming it to _pages and _bvec which is the real semantics - the _rd or _pages gives you a synthetic bvec for each page, and the other one gives you the full bvec.
