Let me address each of your questions in turn:
I'd also be interested to see some analysis about path-based interface vs. file descriptor-base interface. What are cons and pros. E.g. if my path is a symlink, with path-based interface it is not obvious whether I drop caches for the symlink itself or caches of the target.
Note, if there are no answers, fine with me, I am asking just out of curiosity.
