do you mean, if i implement it, you will revert this _hint hack?

of course, nfs client accociates nfs filehandles to vnodes.
how can it work, otherwise?

and you are introducing another obstacle.

why do you want to use arbitrary tag?

you can implement the "generic hash table provider" and make fileassoc use it.
(a too generic interface is likely useless, tho...)
