That's probably reasonable, but it won't be entirely trivial. :-/

Don't change these *after* calling namei. In particular, changing
nameiop is likely to buy you undefined behavior, which could easily
explain the other problems you're seeing.
The closer to ordinary namei interaction you can make your stuff, the
more likely it is to work.
